Severely spalled tie beam caused by rusted rebars.
Spalled Concrete- When the rebars located inside steel reinforced concrete rust the concrete eventually cracks, which in turn weakens the structural members of a building or house (tie beams, columns, slabs). Spalled (cracked) concrete is very common, especially in areas located near bodies of salt water. Concrete is a pourous material and like a large sponge it soaks up the outside elements. The salt in the air speeds up the corrosion process that causes concrete to spall. Concrete may also spall prematurely if the rebars are not adequately covered with concrete. In order to repair spalled concrete, Snapp Industries sandblasts the rusted steel and/or replaces the steel rebars and recovers it with gunite (pnematically sprayed concrete). The use of gunite enables Snapp Industries to repair spalled concrete quickly and affordably.
Pressure Grouting is a method used to restabalize pools, foundations, and footers. Portland cement is pumped beneath the ground in order to fill voids, and/or compact loosely consolidated soils. A hydraulic pump pushes the "slurry" grout material through a hose connected to a hollow galvanized steel pipe. This pipe is driven down to solid base or bedrock before pumping commences. Gradually the grout material works its way up from the solid base until it reaches the bottom of the foundation.

Biltmore II membrane application and spalling repairs.
Membrane application to above grade pools is needed when a pool is leaking. Usually the pools are built above parking garages and/or living quarters. The reinforced concrete that makes the pool shell may be spalled (cracked), which also contributes to the leaking. The picture on the left shows a pool that is in the process of being repaired. The gray patches are areas that were spalled. Gunite was applied to these areas after the steel was replaced.
Pin piles are small-diameter (3 to 4 inch) schedule-40 galvanized pipe, driven with hand-held or excavator-mounted jackhammers. The weight capacity for the above mentioned pin pile is 10,000 lbs. each. Short pipe lengths, usually 5-feet, are used, and are mechanically welded together. They are driven down until they reach solid base or bedrock. This permanantly stops a structure from settling.

Epoxy Injection is a process used to repair all different types of concrete structures. The material fills cracks, and welds them together structurally with an epoxy that is forced through the crack under a high rate of pressure. This procedure forms a bond that is stronger than the original concrete. Snapp Industries has experience epoxy injecting many concrete structures such as pools, parking garages, columns, beams, floor slabs, rib joist, pilings, etc.
Chemical grouting or urethane injection is a method used to seal leaking cracks, fractures, joints and holes in concrete and masonry. When cured, the grout forms a closed cell elastic gasket that stops water with a three way seal by chemical bond, mechanical bond, and compression seal. Snapp Industries, Inc. uses chemical grout to stop leaking water in parking garages, pools, fountains, planters, etc.
