 Sump pumps and battery backups.
The most important part of any internal or external water proofing system is drainage.
That's where a decent sump pump and liner comes in. We favor simple, durable, uncluttered liners for our installs. We also have discreet, almost invisible, discharge options available.
Our liners can be fully perforated to admit ground water or "selectively perforated" for sand and high water table applications. Bolt down lids are fully sealable that sit flat, and can hold up to 200lbs before failure. All units also come with a high water level alarm, and are "battery backup ready".

1. The concrete is broken out in the area of sump pump install. Jackhammers are used and some dust is expected. For people increased sensitivities to dust, we have negative air machines available.
2. a pit is excavated approximately 28"deep and 24" wide to accomodate the sump pump liner. In silty pits we also wrap the liner in filter fabric as an extra line of defense from soupy silt.

 3. The sump pump liner is installed and packed with gravel to prevent silt from getting into the liner through the perforations or any pipe penetrations. Our standard liner is perforated to admit ground water. We also have non-perforated, fully air tight liners for high water table applications and/or radon gas remediation. We do not subscribe to the "one size fits all" theory of sump pump liners. This is the most important part of your sytem and it must be done correctly if it is to last a lifetime!

4. Sump pump is installed on the bottom of the liner. Our standard sump pump is a 1/3hp Barnes sp33 with a vertical float. We favor vertical floats to "wide angle" floats because in our experience the wide angle floats tend to get caught up on the equipment in the liner.

 5th, Discharge pipe is installed through to the exterior. We run all 1.5" rigid ABS or PVC pipe for our discharges. Thin plastic corrugated hoses are cheap and easy to install but all you have to do is sneeze in the general vicinity of these discharge hoses and the hose falls apart. Not so with rigid piping. It is more work to use rigid pipe but the quality of install is far superior.
 6. Concrete is re-poured and trowelled smooth but not just any concrete. When we install an internal dewatering system, we also install gravel and/or a drain track on top of the footing. Therefore, when we re-pour your concrete, the new concrete will be thinner than your old concrete. We all know how important fibre is. So we actually use fibre in our concrete. The fibre reinforces your concrete so it doesn't crack like the cheaper stuff. Although this is far more expensive than regular concrete, we reason that it is less expensive than having to come back to replace your concrete...and less hassle for you; the homeowner!
