Kingstreet – Apartment Building Crawl Space Drainage System

This 4-storey walk up apartment building had a 4-foot high crawlspace that had a severe water problem.  The on-going water issue had been left un-remediated and severe mold growth on the wood floor system resulted.


  • Install an engineered drainage system in crawlspace
  • Install 2000 lineal feet of interior weeping tile
  • Install 6 sump systems
  • Install sump monitoring system with alarms


  • All mold was remediated by a remediation professional prior to our project.
  • A consulting company along with a mechanical engineering firm designed a complicated internal weeping tile system of approximately 2000 lineal feet in length that drained into 6 sump systems.
  • Each sump system was connected to an exterior storm sewer and monitored by a control panel and alarm system.
  • We helped design the project to make it more practical to install. One of the items we came up with was access in and out of a cut-out in the perimeter foundation in two locations. Prior to that, access was to be through a crawlspace floor hatch and down a hallway. The client was happy to not have disruption and mess in the hallways.
  • We had a crew of 12 men and one full-time superintendent complete the project on budget and ahead of schedule in 3 weeks time.
  • Crawlspace was monitored for a period of 3 years as part of our contract with no re-occurring water issue.

What our customers say

I would like to take this opportunity to thank you for a job well done. After this past weekend's deluge, our basement was left completely dry.

We have had our fair share of unremarkable and even troublesome experiences with other contractors, so you guys were certainly a breath of fresh air. An honest contractor, bang on with the timeline, finished on time, within budget, your "nothing is too much trouble" attitude...and a job well done.

(After a record-breaking rainfall in July 2012 and days before we were leaving on vacation, we returned home and) found that our basement was flooded...The Abarent team had done what I thought was impossible. They installed the weeping tile in two days over the long weekend and on a very tight deadline. Their crew was very professional and know what they were doing... Two days before our vacation, the project was complete and we were able to leave and enjoy our family vacation without worrying about flooding.

Abarent provided a 3-page, itemized list of the specific work to be done at each stage of the project, including descriptions of optional issues (including additional costs) that might arise during the work. The company president did the initial walk-through for their estimate and later went through it, line by line. He pointed out potential problems and things we had to prepare for during the work (extra cracks, concrete dust, effects on neighbors, etc.)... Repairing a foundation is a very traumatic event for any householder because all of your house investment is (literally!) in the air. If you have to do it, call Abarent. They are professional - we cannot recommend them highly enough.
