Expansion Joints

The most common basement problem homeowners face, water damage occurs from moisture seeping through porous surfaces, through cracks, construction joints, or structural defects. As damp beams and joists warp, mold-causing fungi and dry rot develops, meaning that structural defects become structural damage. We look at water-seepage problems from the inside to avoid costly exterior foundation work. Our experienced professionals can advise you on the best product to keep your basement dry for years to come.

Within its 20-30 year lifespan, corrugated metal will rust and buckle and need costly replacement. DD Reconstruction uses CentriPipe, AP/M’s centrifugally cast concrete pipe system designed to protect against corrosion and structural renewal of storm and sanitary sewer pipes between 30” to 120” in diameter.

With the CentriPipe system, you avoid the costs associated with digging, repaving, traffic detours, flooding, and unforeseen reconstruction complications. Your replacement pipe is new, 100% environmentally sound, waterproof, and fully sealed—protecting against corrosion— essentially doubling the life of the pipe.

Failed construction joints and cracks, common defects found in concrete, can lead to costly structural deterioration if not repaired. We can assess your structure to repair cracks and joints and will work with you on a prevention plan to extend the life of your concrete.

Storage water tanks are designed with a specific purpose and service life in mind. Therefore, a number of variables can affect a tank’s service life. We take these variables into consideration when assessing your structure for the right waterproofing treatment, extending service life and improving quality through a number of culinary coating options.

Our waterproofing systems improve your deck’s looks and functionality. Based on the specifications of your project, we can make recommendations on the best products and installation methods. We keep your maintenance considerations in mind as we advise you on how best to protect your deck against weather, salt, and regular wear and tear.

DD Reconstruction offers waterproofing solutions for foundations, walls and roofs—for both residential and commercial structures. As water and chemical seepage into cracks is one of the primary causes of structural corrosion, we work to seal from the inside, avoiding costly outside foundation excavation. A waterproofing plan can prevent damage down the line, saving you thousands of dollars.

Whether for a commercial building or residence, we offer a variety of foundation waterproofing options:

• Protect the structure
• Under-slab waterproofing
• Crystalline waterproofing coatings
• Sheet waterproofing
• Fluid-applied installations
• Warranted installations

Split-slabs separate waterproofing and traffic-bearing functions. Single concrete slabs do double duty supporting the structure while working as the traffic surface. This can result in more wear and greater repair costs.

Water is able to pass through the surface of a split-slab installation to a buried waterproofing membrane, giving your structure a longer life.

Under-slab waterproofing controls moisture migration through concrete. Uncontrolled, floor coverings and coatings can be compromised, resulting in the growth of fungus, mildew and mold.

We have extensive experience with the two types of under-slab waterproofing—vapor retarders and vapor barriers. Barriers are sheet or rolled membranes installed beneath the concrete slab. Vapor retarders (such as Xypex) are chemical and non-toxic and can be 50% less expensive to install.

Xypex is a non-toxic chemical treatment used to waterproof and protect concrete. Once applied, Xypex’s crystalline technology reacts whenever water and other liquids are present. The non-soluble crystalline treatment uses the porous and chemical properties of concrete to fill structural pores and capillaries, rendering the concrete impermeable.

Chemicals and acidic compounds in water and wastewater treatment facilities can crack and corrode unprotected concrete. The filtering processes, hard on steel and concrete, require high-performance coating solutions. Wastewater coatings protect sanitary sewer collection systems and wastewater treatment plants from water infiltration and exfiltration, the effects of hydrogen sulfide, and corrosion. Applying these coatings can dramatically increase the life of concrete structures used in these environments.
