Logistics Warehouses & Distribution Centers

Yard drainage, industrial floor drainage and stormwater runoff control in large-scale projects

The Challenge

In a mid-sized distribution center (15,000–50,000 m²), linear meters of HDPE conduit far exceed those of drainage pipe: hundreds of meters of automation, IT, power and fire detection cables run under the slab and across yards, protected by corrugated HDPE conduits (NBR 15715). At the same time, yards supporting 48-tonne trucks require drainage sized for that load — and Brazil’s detention basin requirements mandate stormwater storage for paved areas over 500 m².

Techduto specifies the right conduit and drain for every point of the project: from under-slab conduit to yard collection pipe, drainage blanket and basin sizing.

Challenges and Solutions

How Techduto addresses each challenge in Logistics Warehouses & Distribution Centers

Automation, IT and power cabling under the slab

Techduto NBR corrugated HDPE conduit cast into the slab protects data, power and automation cables; future re-routing requires no concrete cutting.

Lighting circuits and EV forklift charging

HDPE conduit (NBR 15715) in external ducts and under yards protects high-current cables for 10 m high-bay lighting and electric forklift charging stations.

Flooded truck manoeuvring yard

Techdreno DW SN8 collects water from paved yards and withstands truck traffic without deforming.

Fine pumping under industrial floor slab

Drainage geocomposite under the industrial floor eliminates pore pressure and prevents fine pumping that cracks concrete.

Mandatory detention basin

Rational Method sizing and large-diameter HDPE pipes for conveyance and in-line storage, complying with local municipal and state regulations.

Frequently Asked Questions

Common questions about Logistics Warehouses & Distribution Centers

Law 12,526/2007 is specific to São Paulo state, but similar regulations exist in other states and municipalities. The common threshold is impervious area above 500 m². Always verify local legislation before design.

In many projects, yes. The geocomposite provides equivalent hydraulic transmissivity to gravel at a much smaller thickness, reducing excavation depth and aggregate transport costs.

Techdreno DW with SN8 ring stiffness is specified for heavy vehicle traffic. It supports loads up to 48 t with a minimum cover of 0.8 m, in accordance with DNIT 093/2016-EM.

Sizing uses the Rational Method (Q = C·i·A), with return period and restriction flow rate defined by the local authority. Techduto's engineering team supports the calculation.
