Perfect Ground Solutions often get asked to look at lawns that are uneven. Soil will continue to settle and consolidate naturally for five to ten years following building or drainage work. Removal of trees or animal activity (moles, rabbits etc) can also lead to unevenness. The best approaches and timing will depend on the cause of any slumping, the soil type and its existing condition and so, long before we bring in any new soil, we carry out a full investigation of the site.
