Solutions
Five HDPE underground engineering fronts — national reference, 40 years in the market and 4 units across Brazil.
Frequently Asked Questions
Answers to common questions about Techduto solutions, standards and service.
Techduto addresses five fronts of underground engineering with HDPE (high-density polyethylene) solutions: agricultural and urban subsurface drainage, mechanical protection of electrical and telecom cables (NBR 15715), soil stabilization with Bidim geotextile and geocomposite, complete solar plant infrastructure (DC/MV cables, platform drainage, foundations) and the Techdreno 360 System — a turnkey solution for agricultural drainage.
HDPE offers over 50 years of service life buried, immune to corrosion, roots and acidic soils — versus 20–30 years for PVC and ongoing maintenance needs for concrete. HDPE is 95% lighter than concrete and 60% lighter than PVC, reducing logistics costs and installation time. In terms of chemical resistance, HDPE withstands acids, alkalis, oils and agricultural products without degradation.
Techduto solutions comply with ABNT NBR 15715 (corrugated HDPE conduits for buried electrical cables — a standard in which Techduto participated in the technical drafting), ABNT NBR 15073 (HDPE drainage pipes), DNIT 093/2016 (road drainage), as well as factory certifications in ISO. Each product comes with a traceable compliance certificate.
Yes. Techduto operates 4 units in Brazil — three factories (São Paulo, Pernambuco and Mato Grosso) and a Distribution Center in Petrolina-PE — serving each project from the unit closest to the site. Over 260 solar farms, road, rail, agricultural and sanitation projects across all regions of Brazil. A technical team of engineers assists with sizing and installation on large-scale projects.
The choice depends on the specific problem: for excess water in the soil (farm, construction site, solar platform), subsurface drainage with Techdreno; for buried cables in any sector, NBR 15715 conduit with UV or AC additive depending on exposure; for unstable soil or erosion, Bidim geotextile or geocomposite; for integrated agricultural drainage, the Techdreno 360 System. If in doubt, contact our engineering team via WhatsApp.
Correctly installed virgin HDPE products have a service life of over 50 years buried — longer than the typical operating life of a solar plant (25 years), a highway (30 years) or an agricultural drainage system (40 anos). HDPE is immune to corrosion, roots and chemical attack from soil, requiring no preventive maintenance throughout the project's service life.
