Waterlogged garden in new build house

colinbloke

We moved into a brand new house end of January this year. The garden was un turfed and had major waterlogging problems. After lots of complaining to taylor wimpey, they had it surveyed and put in some bore holes to help the drainage (end march), straight after this we turfed it and planted to large flower beds. The weather had improved and the garden seemed ok. Since then we've had so much rain some of our plants have died. We got the landscaper back as we were concerned over drainage, he assured us enough drainage was put in and that it is just the unusual high rainfall and also the fact theres a building site at bottom of our garden and when that is eventually built on the drainage will be better(less run off from building site?)
Today after heavy rain we have some parts of the lawn and flower beds with over an inch of surface water sitting there.
I have dug into own ground there is about 8 -10 inches of clay the bottom few inches are absolutely drenched in water, the next layer is like sandy soil with lots of hardcore in it and extremely difficult to dig through this seems to be a barrier for water draining through. below this is very sandy soil.
Has any one got advice? is it just down to high rainfall or should taylor wimpey buliders get it sorted properly?

Sounds like a typical new build where the top-soil was sold-off before works started and they've just spread the leftover building material about and skimmed with subsoil (clay) and then a inch of topsoil.

TBH, the crazy amounts of rain have soaked everyone's gardens, maybe give it 12 months to see what happens?
