Before applying a waterproofing membrane we evaluate the condition of the underlying surface and may install drainage sheet systems that collect and transport water to drainage outlets, or install surface treatments to level and repair rough concrete or finished decks to create the proper grade.

Carbon Fiber Strapping
There are two different types of cracks which develop in basement walls: one due to flexure (referred to as "out-of-plane" loading); and the other caused by shear ("in-plane" loading). Flexure cracks are typically horizontal and may travel to the corners of your basement wall. Shear cracks are typically diagonal along the wall with the bottom being narrower than the top.
Bowing occurs when the pressure and stress forces impact a larger area and push the foundation wall out of plumb. Dry Basement Solutions treats substantial cracks and bowing of more than 2” with carbon fiber strapping. (For smaller cracks we use polyurethane caulk injection, urethane foam grout, or hydrophobic urethane injection.)
Modern carbon fiber materials provide a cost-effective answer to these foundation stresses. These fibers have remarkable strength and can enhance the flexural capacity of steel reinforced and un-reinforced masonry walls by over four times the original capacity – while simultaneously providing waterproofing. Dry Building Solutions is a certified dealer for StrongHold, a leader in carbon fiber materials.

Coating and Sealants
Parking & Pedestrian Deck Restoration & Sealing
We choose deck restoration and sealing products formulated to provide optimum performance as a traffic-bearing membrane with low temperature crack bridging characteristics and that create a positive bond to eliminate lateral water migration which can lead to serious damage from freeze-thaw action and by carrying corrosive salts to the reinforcing steel.
Expansion Joint Installation/Repair
Whenever there is a joint between concrete slabs, there is the potential for water penetration. Dry Building Solutions offers expansion joint installation at the time the slab is laid, and repair or installation of expansion joints for existing slabs.
Adequately waterproofing expansion joints requires the use of materials specifically designed to do that job. One method we use is applying a self-adhesive HDPE waterproofing membrane over the joint using a specially formulated latex surface treatment. This treatment imparts an aggressive, high tack finish to the treated substrate. Alternately, we may use a filler, such as a hybrid urethane epoxy joint filler or a cellular fiber filler made of cellular fibers securely bonded together and uniformly saturated with asphalt for longevity.
Vapor Barrier Membranes
Vapor barrier membranes are installed to help reduce the penetration of moisture and water vapor through the slab into the structure, thereby helping to reduce fungus, mildew, and mold growth. The membrane also helps reduce radon gas from entering the structure.

Lintel Repair & Replacement
Dry Building Solutions provides both expert lintel repair and lintel replacement services. The solution we recommend will be tailored to the source of the
problem and the structure of the wall.
Rusted Steel Lintel
Lintels are horizontal surfaces open to the full force of the weather. When unprotected metal gets wet, it can rust and corrode, even swelling to multiple times its original thickness putting pressure on the surrounding masonry. Rusted or corroded lintels would be replaced and then coated with a rust-inhibiting paint to resist the weather.
Cracked, Insufficient or Missing Masonry Lintel
When installing or replacing masonry lintels, extra care is taken to calculate the lintel strength needed to restore the structural integrity of the wall. Lintels in masonry should extend six inches beyond the opening to adequately spread the weight into the surrounding wall. Our expertise in repointing, or repairing brickwork, will result in a restored façade that meshes with the original brickwork.
A steel lintel rusted out, causing the bricks to lose their mortar and the bricks to become loose.
Before repointing the surrounding wall after a lintel replacement, vapor barrier fabric is applied to the inner wall.
Through Wall Flashing
Interior finish damage, mold development and wall staining are some of the indicators of a water penetration problem that can be addressed with through-wall flashing, although these are commonly misdiagnosed as roof or window leaks. Therefore it is important to choose an experienced waterproofing contractor like Dry Building Solutions that can accurately diagnose the source of the leak.
Through-wall flashing is commonly made from copper or other noncorrosive metal, and is used at all points where water may enter the wall or in areas that are particularly susceptible to water damage. It extends from the sheathing, across the airspace, and all the way to the exterior of the brickwork.
