Iam a homeowner so bear with me I can imagine the nodding of heads when reading this one! Allright,, I have some questions about work that was done in excavating for pavers. When he dug it out using a bobcat I helped him take some quick measurements but we did not use pull string to verify the slope was correct of the subase. We were also trying to beat a huge storm so we kind of scrambled to load in the base material. 1) Concern do you need to use pull string to verify subsoil slopes correctly (it appeared to slope correctly but I know looks are deceiving) or is the sloping emphasis primarily when adding base material (class5) or is it a must for both. I know u cant or shouldn't adjust slope using your screeded sand........but what about doing so using the base material? #2 We didnt compact subsoil with tamper (tried to beat the rain) One specific area of concern is where the downspout would exit .................the surrounding ground would "pump" when walking on it. Although 2 days earlier we had 1.5 of rain. Obviously this contributed to that problem. So after scrambling to put in the base material and getting a fair amount in ...it rained almost an inch's worth in an hour. Alot of the base material was almost quick sand where it was low (low because we didnt get a chance to grade it fully as by this time it was raining like hell) Dried up later in the day but areas where it was low were extremely mushy when walking on and had puddles. We still need to verify and confirm slope of base material but want to wait until all areas are dry? 2-3 days is that enough time? How big of a hole have I dug for myself here what should I do...... surely it has rained when people were installing the base? Assuming I already dropped the ball on sloping the subase or @ least verifying it with pull string can I correct or enhance the slope by adding more base material (class 5) to achieve a proper slope? How serious is it that the subase wasn't compacted before adding base material . This a patio not a driveway if that is any consolation? Any help/ advice would be appreciated?
