“I am doing a research project on Innovative Uses of Pervious

Concrete. Does anyone have any examples?”

Stacy Turner, PE, USACENPCPA LinkedIn Group Post

Feb 6, 2013

Literature Review/Methodology

• 90% of material was found through internet sources

• Main difficulty – differentiating innovative uses

1. “pervious concrete”: 1550 results.

2. “porous concrete” -“pervious concrete”: 4090 results

3. “no fines concrete” -“porous concrete” -“pervious concrete”: 464 results

Greenhouse Floors

• Eliminate ponding water• Control weed growth• Solid surface for equipment

transport• Heat storage & exchanger for

plants• Must vacuum to prevent

clogging from soils and nursery materials

Reasons:1. Community Relations Tool2. Volunteer friendly – children, seniors3. Supply Parks Dept. with plants

Concerns:1. Clogging with soils & nursery materials2. Severe freeze/thaw winters.3. Prevent moss from growing in the moist environment & creating "slippery” working surface.

Solutions:1. Being careful to NOT drop soils2. Vacuum often (its working)3. So far no moss or other organic growth

Retaining Walls• No-fines concrete backfill• Set concrete exerts no

pressure on wall block• Minimal settlement behind

wall• PC attaches to block &

extends wall mass• Excellent drainage reduces

lateral hydrostatic pressure • Taller walls with less

excavation• Higher production rates
