Standard System

 


Pressure Relief System (Generalized Description)

Utilizing a jackhammer, the basement floor is broken open just past the footing, adjacent to the wall(s) to be serviced. A channel is then excavated along side the footing. (Note: All broken cement and subsoil from the channel will be removed from the premises.)

While the channel is open, holes are drilled in the bottom course of hollow blocks of all accessible foundation walls adjacent to the system to drain out any water that may be entrapped in the blocks. Amount and location of holes will be drilledin the most appropiate manner, as viewed by the forman. (Note: This procedure is eliminated on poured concrete, solid block and stone foundations. The holes will be injected with disinfectant neutralizer to combat bacteria.)

A Polyethylene based felt fabric is laid in the trench, preceded by a four inch (4") perforated pipe and covered by 3/4" Trap Rock. This pipe meets the requirements for drainage pipe as required by the State Code and the requirements of ASTM-F405-74.

The floor is then re-cemented with nylon fiber reinforced concrete then steel troweled smooth to the level of the existing cement. Thickness of the new cement will be determined by the depth of the footing to allow for proper drainage. A full or partial 3/4" gap or mirror drain will be left between the new cement and the foundation wall. This is known as a "floating floor" and is now required by many towns on all new construction. (Note: Gap is usually wider on stone foundations.)

The under-floor piping system usually leads to a sump pump which is installed in PE crock with a PE cover. Crock and pump are below floor level and the only exposed portion will be the 11/4" discharged line. Location of pump and discharge line will be at the discretion of the foreman with customer's wishes considered.

Note: It is also the responsibility of the customer to provide a grounded electrical outlet for the pump.

A demustification spray shall be used upon completion of job to improve air quality.

Premises will be left "broom clean" but customer should cover all items of value that might be soiled or damaged. Thank You For Your Confidence In Our Company.

American Basement Company, Inc. recommends the use of a dehumidifier or proper ventilation to reduce the effects of condensation.

During the curing process there will be evidence of sweating on top of the freshly poured concrete in various areas. DO NOT BE ALARMED if during the first 90 days following the completion of the work on your basement, leaking appears to continue. The system needs at least 90 days to set up and cure. Please be patient during this period, especially if heavy rains fall.
