The CleanSpace® Crawl Space Contractor Network is a division of Basement Systems, Inc. -- the largest network of basement and crawl space contractors worldwide. Basement Systems was founded in 1987, and consists of a network of more than 300 dealerships.
The CleanSpace® division has been in operation since 2001, and serves in nearly every part of the United States and Canada. CleanSpace® dealers are local, independently owned and operated companies that are united under the common goal of creating drier, healthier, and more energy efficient crawl spaces. We are not a franchise!
Each CleanSpace® dealer works with the network cooperatively, sharing knowledge, experiences, and best practices with one another. We also employ a full-time Research and Development Department tasked with keeping us on the cutting edge.
Clean CrawlSpace Inc. is the local CleanSpace® Dealer in San Francisco, San Jose, Fremont, and the surrounding areas in California. Call us today at 1-866-379-2729 or contact us online to get a free estimate on crawl space repair and encapsulation for your home.
Each year, Basement Systems hosts an Annual Convention, which is a week-long gathering that includes trainings, product unveilings, and dealer awards.
Not just anyone can become a member of our network! We carefully hand-pick our dealerships from well-established, accomplished companies that are stable and reputable within their local area. Our dealers are experts in the industry, specializing in crawl space repair and moisture control as a core function of their business. These are specialists who work exclusively in crawl spaces every day!
The Better Business Bureau has recognized us several times for our accomplishments. Among others, Basement Systems has been awarded the BBB Marketplace Ethics Award multiple times, the BBB Consumer Education Award multiple times, and the BBB Quality Award.
Dealer Support & Training
As members of the CleanSpace® Network, dealers also benefit from year-round training sessions provided at the headquarters, free of charge. These trainings focus on every aspect of the business, including customer service, sales, installation, system maintenance, and much more.
Dealers also take our in-house Certification Testing upon the completion of each training. Along with our full-time Research And Development Department and Training Team, the headquarters also maintains a fully staffed Dealer Support Department.
This is a team of highly qualified industry experts, who are standing by every day to provide expert advice on unique challenges that our dealers face as they work in crawl spaces all over North America.

Determination of Capacity
The ultimate capacity of a helical anchor may be calculated using the
traditional bearing capacity equation:
Qu = ∑ [Ah (cNc + qNq)]
Where:
Qu
=
Ultimate Anchor Capacity (lb)
Ah
=
Area of Individual Helix Plate (ft2)
c
=
Effective Soil Cohesion (lb/ft2)
Nc
=
Dimensionless Bearing Capacity Factor = 9
q
=
Effective Vertical Overburden Pressure
(lb/ft2)
Nq
=
Dimensionless Bearing Capacity Factor
Total stress parameters should be used for short-term and transient
load applications and effective stress parameters should be used for
long-term, permanent load applications. A factor of safety of 2 is
typically used to determine the allowable soil bearing capacity,
especially if torque is monitored during the helical anchor
installation.
Like other deep foundation alternatives, there are many factors to be
considered in designing a helical anchor foundation. Supportworks
recommends that helical anchor design be completed by an experienced
geotechnical engineer or other qualified professional.
Another well-documented and accepted method for estimating helical
anchor capacity is by correlation to installation torque. In simple
terms, the torsional resistance generated during helical anchor
installation is a measure of soil shear strength and can be related to
the bearing capacity of the anchor.
Qu = KT
Where:
Qu
=
Ultimate anchor Capacity (lb)
K
=
Capacity to Torque Ratio (ft-1)
T
=
Installation Torque (ft-lb)
The capacity to torque ratio is not a constant and varies with soil
conditions and the size of the anchor shaft. Load testing using the
proposed helical anchor and helix blade configuration is the best way
to determine project-specific K-values. However, ICC-ES AC358 provides
default K-values for varying anchor shaft sizes, which may be used
conservatively for most soil conditions. The default value for the
Model 150 Helical Anchor System (1.50" square shaft) is K = 10
ft-1.
The cross-section of a square shaft is very compact which can allow
the anchor to penetrate more easily through the soil. This compact
shape also reduces the stiffness of the cross section and introduces
more potential for buckling. These two factors make square shaft
helical anchors better suited for tension loads. Supportworks, Inc.
therefore recommends their use mainly for these types of applications.
Square shaft helical anchors (piles) used in compression should be
evaluated on a case by case basis by the project engineer.
Mechanical Axial Capacity (see note):
Allowable Tension = 26.5 kips*
* The mechanical tensile capacity of the Model 150 Helical Anchor
System is limited by the allowable stress levels dictated by AISC for
a high strength bolt in double shear. The allowable tensile capacity
of the shaft is actually much higher than this Allowable Tension
value.
Torque Limited Axial Design Capacities based on Ultimate Torsional
Resistance of Anchor Shaft = 6,340 ft-lbs**:
Ultimate Soil Capacity = 63.4 kips** (with K = 10 ft-1, see note)
Allowable Soil Capacity = 31.7 kips (FOS = 2, Allowable System
Capacity therefore governed by mechanical capacity = 26.5 kips*)
** This Ultimate Torsional Resistance and its corresponding Torque
Limited Capacities are based on laboratory test results from an IAS
accredited facility and may only be approached in idealized
conditions. Plastic torsional deformations can begin in the anchor
shaft near 4,600 ft-lbs. This value may be reached and exceeded in the
field by maintaining alignment between the anchor and the drive head,
limiting impact forces and torque reversal, and reducing the tendency
to "crowd" (push down on) the anchor. Installation through soils with
obstructions or high variability may result in impact loading on the
anchor. In these cases, achieving high torque values becomes more
difficult and a further reduction in the Design Torque Limit may be
appropriate.
Note
K = 10 ft-1 is a default value as published in ICC-ES AC358
which can, in many cases, be considered conservative. Higher
capacities can often be achieved with site-specific load testing.
Allowable capacities based on site testing shall not exceed the
Mechanical Axial Capacity.
Each member of the CleanSpace® Network provides homeowners in their service area with free written quotes for all repairs and upgrades for their crawl space.
Each quote includes a professional, on-site inspection and measurement of your crawl space. We'll answer any questions you have, and map out your crawl space using our innovative crawl space software program. Your specialist will take you shopping through our products, making recommendations on which options would work best for your scenario.
As an added courtesy, your local dealer will also mail along a full-color copy of our crawl space book: Crawl Space Science. This provides you with a powerful research tool -- one that is filled with photos and information about crawl spaces, as well as details about our products and services.
