2. CHALLENGING SUBSOIL
CONDITIONS
Due to the treacherous subsoil conditions in the
Gulf Coast area, characterized by loose sands and
expansive clays, it is essential to conduct a
thorough geotechnical investigation before
designing and constructing inground swimming
pools.

3. SHALLOW GROUNDWATER
ASSESSMENT
Given the presence of shallow groundwater in the
region, assessing groundwater levels is crucial
during the geotechnical exploration to understand
its impact on pool construction.

4. STRUCTURAL
CONSIDERATIONS
The geotechnical investigation should encompass
an evaluation of structural considerations, as pools
built in expansive clays can experience substantial
movement problems and structural distress if not
properly designed.

5. DRAINAGE AND SLOPE
ANALYSIS
Comprehensive pool design should take into
account factors such as drainage, the presence of
trees, and slope conditions on the site to mitigate
potential issues.

6. HOUSTON AREA POOLS
Recognizing the prevalence of inground swimming
pools in the Houston area, it's imperative to address
the issues of movement and cracking that some
pools in the region have experienced. The study
aims to establish best practices for the design and
construction of pools to safeguard public safety
and the interests of pool contractors.

7. GEOTECHNICAL
EXPLORATION AND SOIL
BORINGS
The geotechnical engineer licensed in the State of
Texas should conduct a geotechnical exploration.
This exploration will involve drilling soil borings at
the pool's intended location. The depth of these
borings should be at least twice the depth of the
pool, with a minimum depth of 20 feet.

8. BORING REQUIREMENTS
Depending on the pool's size, the number of
borings required should be determined. For pools
under 3000 sq. ft., a minimum of two borings is
recommended. For larger pools exceeding 3000
sq. ft., additional borings should be performed,
with at least one boring for every additional 1500
sq. ft. of pool area. These borings are critical for
assessing the subsurface conditions and ensuring
safe and reliable pool construction.
