New Mexico Building Code
for Adobe 1982
The following is an amendment by the State of New Mexico, which
replaces Section 2405 of the Uniform Building Code, for "Unburned Clay
Masonry." It was adopted in 1982.
Part 0—Engineering Regulations— Quality and Design of Materials of Construction
CHAPTER 24— MASONRY
UNBURNED CLAY MASONRY
Sec. 2405.
(a) General. Masonry of unburned clay units shall not be used in any building more
than two 121 stories in height. The height of every wall of unburned clay units without
lateral support shall be not more than ten (10) times the thickness of such walls. Exterior
walls, which are laterally supported with those supports located no more than 24 feet
apart, are allowed a minimum thickness of 10 inches for single story and a minimum
thickness of 14 inches for the bottom story of a two story with the upper story allowed a
minimum thickness of 10 inches. Interior bearing walls are allowed a minimum thickness
of 8 inches, Upward progress of walls shall be in accordance with acceptable practices.
0b1 Soil. The best way to determine the fitness of a soil is to make a sample brick and
allow it to cure in the open, protected from moisture. It should dry without serious
warping or cracking. A suitable adobe mixture of sand and clay shall contain not more
than 2% of water soluble salts, -
(c) Classes of Earthen Construction
(1) Stabilized Adobes. The term "stabilized" is defined to mean water resistant
i adobes made of soils to which certain admixtut s are added in the manufac-
Wring process in order to limit the adobe's water absorption. Exterior walls
constructed of stabilized mortar and adobe require no additional protection.
Stucco is not required. The test required is for a dried four -inch 14 ") cube cut
from a sample unit shall absorb not more than two and one -half percent
moisture by weight when placed upon a constantly water saturated porous
surface for seven (7) days. An adobe unit which meets this specification shall
be considered "stabilized"
(2071
•
Appendix A New Mexico Building CodO for Adobe 1982
121 Untreated Adobes. Untreated adobes are adobes which do not meet the water
absorption specifications. Use of untreated adobes is prohibited within 4
inches above the finished floor grade. Stabilized adobes and mortar may be
used for the first 4 inches above finished floor grade. All untreated adobe shall
have an approved protection of the exterior walls.
(3) Hydraulically Pressed Units. Sample units must be prepared from the specific
soil source to be used and may be tested in accordance with approved test
procedures.
(4) Terrones. The tens terrone shall refer to cut sod bricks. Their use is permitted
11 units are dry and the wall design is in conformance with Sec. 2405 (a).
(5) Burned Adobe. The term "burned adobe" shall refer to mud adobe bricks
which have been cured by low temperature kiln firing. This type of brick is not
generally dense enough to be "frost proof" and may deteriorate rapidly with
seasonal freeze -thaw cycles. Its use for exterior locations is discouraged in
climate zones with daily freeze -thaw cycles.
(61 Rammed Earth.
1) Soils: See Section 2405 (b).
2) Moisture Content: Moisture content of rammed earth walls shall be suitable
for proper compaction.
3) Forms: Suitable forms shall be used.
4) Lifts and Compaction: Uncompacted damp soil shall be compacted in lifts
not to exceed 6" until suitable compressive strength is achieved.
5) Tests: Testing of rammed earth construction shall be in accordance with
approved standards.
61 Curing: The building officials may allow continuous construction of
rammed earth prior to the full curing process, provided proper compaction
methods are followed.
(d) Sampling. Each of the tests prescribed in this section shall be applied to sample
units selected at random at a ratio of 5 units/25,000 bricks to be used or at the discretion of
the building official.
(e) Moisture Content. The moisture content of untreated units shall be not more
than four percent by weight.
(f) Absorption. A dried four -inch (4 ") cube cut from a sample unit shall absorb not
more than two and one -half percent moisture by weight when placed upon a constantly
water saturated porous surface for seven (7) days. An adobe unit which meets this specifi-
cation shall be considered "stabilized ",
(g) Shrinkage Cracks. No units shall contain more than three shrinkage cracks, and
no shrinkage crack shall exceed two inches (2 ") in length or one- eighth inch (} ") width.
(h) Compressive Strength. The units shall have an average compressive strength of
300 pounds per square inch when tested in accordance with ASTM C - 67. One sample out
of five may have a compressive strength of not less than 250 pounds per square inch.
(i) Modulus of Rupture. The unit shall average 50 pounds per square inch in modulus
of rupture when tested according to the following procedures:
1) A standard 4 X 10 X 14 cured unit shall be laid over (cylindrical) supports two
inches (2 ") from each end, and extending across the full width of the unit.
2) A cylinder two inches (2 ") in diameter shall be laid midway between and paral-
lel to the supports.
3) Load shall be applied to the cylinder at the rate of 500 pounds per minute until
rupture occurs.
3WL
4) The modulus of rupture is equal to 2Bd 2
W = Load of rupture
L = Distance between supports
8 = Width of brick
d = Thickness of brick
Footnote: Tests for pressed units is presently being developed.
(j) Mortar. The use of earth mortar is allowed if earth mortar material is of same type
[208]
New Mexico Building Cctde for Adobe 1982
as the adobe bricks. Conventional lime /sand/cement mortars of Types M, S, N, are also
allowed.
Mortar "bedding" joints shall be full SLUSH type, with partially open "head" joints
allowable if surface is to be plastered. All joints shall be bonded (overlapped) a minimum
of 4 ".
• (k) Use. No adobe shall be laid in the wall dependent on weather conditions until
fully cured.
(1) Foundations. Adobes shall not be used for foundation or basement walls. All
adobe walls, except as noted under Group M Buildings, shall have a continuous concrete
footing at least eight inches (8 "1 thick and not less than two inches 12 ") wider on each side
that support the foundation walls above. All foundation walls which support adobe units
shall extend to an elevation not less than six inches 16 ") above the finish grade.
Foundation walls shall be at least as thick as the exterior wall as specified in Section
2405 (1). Where perimeter insulation is used, a variance is allowed for the stem wall width
to be two inches 12 ") smaller than the width of the adobe wall it supports. Alternative
foundation systems shall be approved by the building official.
All bearing walls shall be topped with a continuous belt course or tie beam (except
patio walls less than 6 feet high above stern). See "o" isolated piers.
(m) Tie Beams.
11 Concrete. Shall be a minimum of six inches 16 ") thick by width of top of wall. A
bond beam centered to cover 3 of the width of the top of the wall by 6" inch
thick shall be allowed for walls wider than 10'. All concrete tie beams shall be
reinforced with a minimum of two No. 4 reinforcing rods at each floor and
ceiling plate line. All bond beam construction shall be in accordance with
accepted engineering practices.
2) Wooden Tie Beam. Shall be a minimum of 6" wall thickness except as provided
for walls thicker than 10" above. Wood tie beams may be solid in the six inch
(6 ") dimension or may be built up by applying layers of lumber. No layer shall
be less than one inch (1 ").
(n) Wood Lintels. Shall be minimum in size six inches (6 ") by wall width. All ends
shall have a wall bearing of at least twelve inches (12 "). All lintels, wood or concrete, in
excess of nine feet 19') shall have specific approval of the building official. The building
official shall approve all wooden tie beams for walls thicker than ten inches (10 ").
(o) Anchorage. Roof and Boor structures will be suitably anchored to tie beams.
Wood joists, vigas or beams shall be spiked to the wood tie beam with large nails or large
screws.
Fireplaces shall be secured to the wall mass by suitable ladder reinforcement such as
"durowall" or equivalent.
Partitions of wood shall be constructed as specific in Chapter 25, wood and metal
partitions may be secured to nailing blocks laid up in the adobe wall or by other approved
methods.
(p) Plastering. All untreated adobe shall have all exterior walls plastered on the out-
side with Portland cement plaster, minimum thickness'♦" in accordance with Chapter 47.
Protective coatings other than plaster are allowed, provided such coating is equivalent to
Portland cement plaster in protecting the untreated adobes against deterioration and/or
loss of strength due to water. Metal wire mesh minimum 20 guage by one inch (1 ") opening
shall be securely attached to the exterior adobe wall surface by nails or staples with
minimum penetration of one and one -half inches 111"). Such mesh fasteners shall have a
maximum spacing of sixteen inches 116 ") from each other. All exposed wood surfaces in
adobe walls shall be treated with an approved wood preservative before the application of
wire mesh. Alternative plastering systems shall be approved by the building official.
EXCEPTION: 1) Exterior patio, yard walls, etc. need not have Portland cement coating.
lq) Floor Area. Allowable floor area shall not exceed that specified under Occupancy.
Adobe construction shall be allowed the same area as given in Type V -N constniction.

Re: Subsurface Soils Exploration
Lot 3, Cottonwood Hollow Subdivision
Garfield County, CO
Dear Mr. Forbes:
As requested, Lincoln DeVore personnel have recently completed a
geotechnical exploratory program at the above referenced site.
one shallow exploration pit was excavated within the building
pad to determine as closely as possible the soil types which
exist beneath the proposed structure. An additional exploration
pit was excavated in the area of the proposed on -site sewage
disposal field and utilized for percolation testing. Our conclu-
sions and recommendations for this site are presented below.
Soil Classification: The soils on this site are quite variable,
ranging from four feet of fine grained, sandy silt to silty sands
with scattered cobbles from four to six feet and fine sandy silt
from a depth of six to nine feet. The total depth of the explo-
ration pit was nine feet. The allowable bearing capacities of
these soils are 1100 psf maximum and 150 psf minimum for the
sandy silts in the upper four feet of the soil profile. The
allowable bearing capacity for the gravelly, sandy silts encoun-
tered below four feet can be taken as 1400 psf maximum and 250
psf minimum.
Man -made Fill: The soils encountered in our exploration pit
appear to be native to the site. All building foundations must
penetrate any man -made fills which are present at the site at
this time, as well as any fills which result from the excavation
process. Careful examination of the open excavation will be
necessary to determine the presence or absence of man -made fills.
The open excavation must be examinedpriorto the placement of
concrete to establish that materials of proper design bearing
capacity have been exposed and that no soft spots or debris are
present in the foundation area. A 24 hour notice is required for
all field examinations to enable Lincoln DeVore to schedule
personnel and provide service when needed.
Soil Moisture Conditions: High - NO FREE WATER OBSERVED
Jo
Mr. Forbes
SSE Lot 3, Cottonwood Hollow Sub.
April 14, 1993 Page 2
The high moisture observed on this site appear to be the result
of snow melt and precipitation.
Foundation Type Recommended: A properly designed shallow foun-
dation system based on the above allowable soil bearing capaci-
ties would be appropriate for use on this site.
Voids Beneath Foundation Walls: Depending upon the final depth
of excavation, the loading characteristics of the individual
structure and the foundation type ultimately decided upon for the
on -site soil conditions, void material placed in the bottom of
the foundation walls may be required. If such void is required,
the foundation design should be carefully followed.
Reinforcing: The foundation should be reinforced as shown on
the foundation design. 1.,. = c . r, r, u ,
All foundation stem walls should be designed as "grade beams"
capable of spanning at least twelve feet. Where the foundation
stem walls are relatively shallow in height, vertical reinforcing
will not be necessary. However, in the walls retaining soil in
excess of four feet in height, vertical reinforcing may be neces-
sary to resist the lateral pressures (restrained case) of the
soils along the wall exterior. To aid in designing such vertical
reinforcing, an equivalent fluid pressure (E.F.P) on the order of
50 pcf would be appropriate.
Floor Slabs: Floor slabs on grade, if any, should be positively
separated from all structural portions of this building and
allowed to float freely. Frequent scoring (control joints) of the
slabs should be provided to allow for possible shrinkage cracking
of the slab. These control joints should be placed to provide
maximum slab areas of approximately 200 to 360 square feet. Any
man -made fill placed below floor slabs on grade should be com-
pacted to a minimum of 90% of its maximum Modified Proctor dry
density, ASTM D -1557. These soils should be placed at a moisture
content conducive to the required compaction (usually Proctor
optimum moisture content +2 %.
Drainage and Grading: Surface grading should be completed in
such a manner that all runoff moisture is removed from the vicin-
ity of the structure as quickly as possible. It is recommended
that a minimum surface gradient of 8% be maintained away from the
structure for the first ten feet. Roof downspouts and sill cocks
should be carried across all backfill areas and allowed to dis-
charge well away from the building. All lawn sprinkling heads
should be placed at least ten feet away from the foundation.
Future owners of this structure should be advised to fill in any
settled yard areas to eliminate ponding of water near the struc-

ture and to provide adequate slope for proper drainage away from
the structure and off the site at all times.
Provided all recommendations found herein pertaining to site
surface drainage, grading and soil compaction are closely fol-
lowed, a perimeter foundation drain would not be required. For
fully finished basements, however, the use of a perimeter founda-
tion drain would significantly reduce potential moisture related
problems which can arise from subsequent area development.
Backfill: To reduce settlement and aid in keeping water from
reaching beneath this building, all backfill around this building
should be mechanically compacted to 80% of its maximum Modified
Proctor dry density ASTM D -1557. The only exception to this would
be the components of the perimeter foundation drain, if any. All
backfill should be composed of the native soils and should notbe
placed by soaking, jetting or puddling. All backfill placed in,,,
utility trenches around this structure or below foundation walls
should be mechanically compacted to a minimum of 90% of its
maximum Modified Proctor dry density ASTM D- 1557. These soils
should be placed at a moisture content conducive to the required
compaction (usually Proctor optimum content ±2 %.
Cement Type: Type II, Type I —II or Type II -V cement is
recommended for all concrete which is in contact with the soils
on this site. Calcium chloride should not be added to a Type II,
Type I —II or Type II -V cement under any circumstances.
Remarks: The bottoms of all exterior foundations should be
located a minimum of 24 inches below finished grade for frost
protection.
Senate Bill 13 Discussion: This particular residence is being
constructed on foundation soils which do not possess a "signifi-
cant potential for expansion ". We recommend that the owner re-
ceive a copy of this summary report of our soil analysis and site
recommendations.
