GC Service Brief
Permeable concrete paving provides stormwater management through pavement surfaces that allow water infiltration into underlying base materials and soils. This approach reduces runoff volumes, decreases drainage infrastructure requirements, and may contribute to green building certifications and municipal stormwater requirements. Permeable systems are increasingly specified for commercial parking lots, plaza areas, and developments with limited stormwater detention capacity.
Pervious concrete uses carefully proportioned concrete mixes with reduced fines that create interconnected void spaces allowing water passage. Proper mix design, placement, and curing are essential for achieving both structural performance and infiltration capacity. We work with concrete suppliers to specify and verify pervious concrete performance.
Permeable interlocking concrete pavers (PICP) use specially designed units with joint spaces filled with permeable aggregate. Water flows through joints into reservoir base materials that provide temporary storage and gradual infiltration. PICP systems offer design flexibility and easier maintenance access than monolithic pervious concrete.
Base system design determines overall infiltration capacity and structural support. Open-graded aggregate reservoirs store water during storm events while allowing gradual infiltration. Geotextile fabrics prevent soil migration while allowing water passage. Underdrains may be required where soil infiltration rates are insufficient.
As a general contractor, we deliver complete permeable paving systems including base construction, surface installation, and maintenance documentation. Direct contracts ensure accountability for both structural and stormwater performance.
