Big space filled with wafer under my garage
« on: September 20, 2017, 03:50:23 pm »
I bought a house in November 2015 and recently found very wide and deep space filled with water under the garage, attached. I and neighbour have notified this issue to the builder but they keep saying this is normal as it was built with 'block and beam' technique.
So we are looking for surveyor to investigate more in detail.

The water seems just stay inside and probably the space is expanding, so looking quite risky to me in safety.

Anybody with knowledge on this kind of construction and can advise ?

Yes this is a block and beam floor. The space under it should be ventilated so it can dry out.

The two propbale causes for this water being parents are:
1) You have a leaking water main or plumbing leak. Turn the stop cock off (under the kitchen sink usually) and see if the water meter is still going round. You reading should be sky high too!

2) The  most likely cause is that the air bricks that ventilate the under floor void are level or below the finished ground level or your drive. This means that all surface rainwater in the area can simply drain under the garage floor far quicker than it will ever soak away or dry out.

Quite why housebuilders and more importantly their site managers, seem incapable of getting the levels right so these are above ground I just don't know.

I know what your problem is without even seeing it!  So why is your housebuilder  (name and shame them!) not at the very least visiting your home to see it?  I would insist they sort this out failing that make a claim on your new home warranty.

This defect cannot be ignored any longer!
