Waterproofing, Crack Injection
-
Waterproofing:
Basements, reservoirs, tanks, tunnels, overhead decks, garages, parking garages, stairwells, underground vaults are examples of structures RE-TECH has successfully applied proven waterproofing products and techniques.
General areas of restoration and some of our techniques are expansion joints, surface applications, and crack injection.
Expansion Joints
RE-TECH Corporation installs E.V.A. foam expansion joints in new or old construction.
E.V.A. is an expanded closed cell cross-linked, preformed expansion joint manufactured from Ethylene Vinyl Acetate. E.V.A. is both elastic and cellular, and will function in both compression and tension without bulging.
The system can accommodate any joint movement, including vertical sheer, deflection, vibration, transverse, longitudinal, lateral sheer and rotation. The minimum tensile strength of E.V.A. is 50 p.s.i. and the minimum elongation at the break is 200%.
For weather control in joints we also install a variety of caulks on new or existing construction. Cold weather installation of Polyurea compounds for a flexible, sealed joint can be done even in below zero temperatures. Fast set compounds are employed where necessary to minimize down-time in working, around the clock structures such as parking garages.
Waterproofing Materials
Cementitious:
We use a method developed to cause a catalytic reaction which in turn generates a non-soluble crystalline formation of dendritic fibers within the pores and capillary tracts of the concrete. Crystalline waterproofing has (fixed size) air spaces so small that water molecules cannot pass through. However, it does allow the passage of air, thus the concrete is able to breath and become thoroughly dry, preventing water vapor buildup.
This process makes it possible to waterproof concrete structures from either the positive or negative side against hydrostatic pressure. The concrete is also protected against spalling, efflorescence, pop-outs, and other damages caused by weathering, de-icing chemicals, bleeding of salts and internal expansion and contraction during the freeze-thaw cycles. It also protects any reinforcing steel from deterioration caused by oxidation and electrolytic corrosion caused by chloride ions.
We are factory authorized applicator/distributors for XYPEX Waterproofing chemicals.
Polymer:
A coating method of positive side waterproofing is also offered on existing structures when excavation is not desired or not possible. This method is pin-point injection. A method where we air-drill pipes below ground to the point desired and inject hydro-active Urethane which both plugs any size hole, void and/or sets a membrane in place to prevent further unwanted migration or flow of water into living or working spaces. This method is also employed in soil stabilization.
RE-TECH Corporation also applies a host of decorative and/or protective, or non- skid safety coatings; and, penetrating sealers and elastomerics for defense against water penetration as well as coatings that discourage graffiti.

Injection crack repair
-
Crack Repair and Injection:
Injection of structural and flexible epoxy resins, and other chemical grout materials by means of pulse regulated pumping machines as well as individual injection capsules and other manual methods are provided for structural rehab as well as liquid proofing measures. Surface mount injector ports or drilled, pressure controlled packers are used on hairline and larger cracks.
Other crack repair methods are also offered for sealing moving cracks by routing out and filling with flexible epoxy, Polyurethane, Polyurea or other sealant. Some of our materials can be installed in temperatures down to -10 degrees F. Fast set materials (in minutes) allow customers to limit the down time of their facility.
