Magruder & Pervious Concrete - A History

During the early 1980’s Magruder Construction’s personnel were among the first, and to date remain the leader in pervious concrete construction. Although pervious concrete was initially only approved as a porous pavement under the drip lines of trees, Magruder's personnel soon saw the importance of its permeability in storm water control and expanded its construction of the ridged pervious pavement to a continuous ribbon or train though out the parking lots. This ribbon or train is the source of capturing storm water which aloud the water to pass through the pervious pavement and “perk” into the porous soil below. These early applications were placed directly on compacted soils and were designed essentially the same as other impermeable pavements such as conventional concrete and asphalt. Many of these early applications remain in use today without any overlay requirements. Magruder Construction’s more recent applications have involved the placement of pervious concrete pavements over a layer of clean gravel or crushed stone. This layer acts as a structural base and as an onsite storm water detention basin. This dual-use design saves the developer a significant amount of money due to the fact it will greatly reduce, if not eliminate all together, the need of any conventional storm water infrastructure. This application may be applied where soils or not as porous as the sandy soils found in Florida. 

Magruder Construction’s quality control personnel will help in assuring the pervious concrete mix design is produced with the correct amounts of Portland cement, coarse aggregates along with water and add mixtures to insure a quality high strength product.

The placement of the pervious concrete itself is of course another area where a elevated level of quality control must be performed. This high level of quality control along with highly experienced personnel has propelled Magruder Construction as the profound leader in the previous concrete pavement industry.
