Are there any pool builders or someone experienced with concrete here? We are wanting to add a sunroom to the back of our house, however only way to get to area is for equipment (mini backhoe) to drive on concrete around pool. Or come in other side which is septic. Pool is 25 years old, will the equipment damage concrete or pool lines under concrete? See photos...(septic is between house and pool house- want sunroom where picnic table is)
