RE: Project #1) In the scope of the work plan review for
permitting the process of stabilizing an interior concrete slab, on grade,
for a 2000 sq. ft. existing dwelling unit that was built in 2001, the
application consists of injecting pressurized structural polyurethane resin
through the slab, on grade, by using core drilled holes in which the
polyurethane resin expands to lift/stabilize the concrete slab. This process
has no control of the path of flow for the polyurethane resin in which direct
contact with the slab on grade concrete is possible. Question –
Does injecting this pressurized structural polyurethane resin for
soil stabilization thru the slab on grade for existing dwellings, with
possible direct contact with the concrete slab on grade, constitute a
violation of 2010 FBC-R Section 318.5? Answer: No. The application of Section R318.5 of the
FBC, Residential is limited in scope to new construction. RE: Project
#2) In the
scope of the work plan review for permitting the process of stabilizing an
exterior foundation/footer for a 1450 sq. ft. existing dwelling unit that was
built in 1985, the application consists of injecting structural polyurethane
resin in the ground outside of the existing dwelling unit to provide
structural support for the foundation /footer. This process has no
control of the path of flow for the polyurethane resin in which direct
contact with the foundation/footer is possible. Question - Does injecting this structural polyurethane
resin into the ground outside the existing dwelling unit with possible direct
contact with the foundation/footer constitute a violation of 2010FBC-R
318.5? Answer: No. The provisions of Section R318.5 of the FBC,
