"Groundworks were contracted to encapsulate the crawl space, with a dehumidifier, intellijacks & sump pump. The inspector showed us pictures & videos of what the work would look like on completion, & explained how each solution would be installed. They tried to charge me more for vent covers until I showed them the contract covering this part. The foreman told me there was a reset button for the sump pump to be installed on an exterior wall, but they did not install it, instead said they would put in a service order. I haven’t heard anything about this issue yet. When they installed the moister barrier, they excluded the cement pads I was told it cost extra to have them covered. When I signed the contract, I was never told there would be extra charges for vent covers or cement pads to be covered. The contract I signed covered a complete encapsulation, but this is not what I got. This is a bait & switch. I would not recommend Groundworks."

"Alex is incredibly honest, pragmatic and helpful. He assessed our community’s potential need and proceeded to discuss any potential restrictions on drainage with the county. We are restricted due to the infrastructure in the proposed drainage area - his thoroughness lost him work but gained our respect. We will look to him for any and all similar projects in the future."

The amount of space that one yard of concrete covers depends on your desired thickness. The thicker the concrete is, the greater the volume it needs to fill to cover the same surface area. With four inches of thickness, one cubic yard of concrete covers 81 square feet. With five inches of thickness, one cubic yard covers 65 square feet. With six inches of thickness, one cubic yard covers 54 square feet.
Ready-mixed concrete in its wet form lasts about 90 minutes to two hours, so it’s important to schedule your concrete delivery accurately. From the time water gets added, a truck has up to 300 rotations of the barrel to deliver the wet concrete. The warmer the temperature, the faster the product sets.
Bags of dry concrete mix have a typical shelf life of a few months if stored in an airtight container with controlled temperature and humidity. The cement reacts to moisture in the air, losing its strength over time.
Most large concrete trucks can hold a maximum of 11 to 15 cubic yards of concrete. However, weight limits on most roads can limit this capacity to around eight to 11 cubic yards per delivery. For context, you’ll need three to four truckloads of concrete to pour a 10-inch foundation for a new home that covers 1,000 square feet.
Assuming the work site has been fully prepped and is reasonably accessible for the concrete delivery truck, pouring one cubic yard of concrete takes about 10 minutes on average. A fully loaded truck with 10 cubic yards of concrete takes around one hour and 40 minutes of continuous pouring to empty its barrel.
