Installation guides, material comparisons, standards and price guidance from the SIGMA Geosynthetics team — to help you specify, compare and install the right geosynthetic for your project.
Guide Why a French drain's perforated pipe gets wrapped in a nonwoven geotextile filter, when you still need gravel, when you don't, and how to install a French drain that doesn't silt up in two seasons.

Guide How geocell (cellular confinement) stabilizes a soft road base, holds fill on a slope and turns a parking area into grass pavers — what it does, where it fails, and the install details that decide it.

Standards How a geotextile spec ties tensile strength, CBR puncture, sampling and acceptance to ASTM and GRI test methods — and how to read a test report so the delivered fabric actually matches the spec.

Guide How to install an HDPE pond liner for shrimp and fish ponds, and what drives the price — thickness (down to 500 micron), pond area, welding and accessories — so you can budget and quote it right.

Standards The international standards behind a road-embankment geotextile spec — ASTM D4595 wide-width tensile, ASTM D4833 puncture, GRI test methods and the IS codes used in India — what each one fixes and how acceptance works.

Pricing HDPE geomembrane price scales almost linearly with thickness — 0.5 mm to 2.0 mm. What else moves the HDPE liner price (virgin vs recycled resin, width, textured), and how to compare quotes in India per m².

Guide Field guide to wick drain installation over a geotextile blanket for soft-ground treatment — why you lay the geotextile first, the install sequence, drain spacing, and what to check at acceptance.

Pricing Geotextile fabric price tracks two things: GSM (weight) and strength class (kN/m or TS). How to read a geotextile price in India per m², and how to compare woven vs non-woven quotes like for like.

Guide How to lay geotextile fabric for road construction and drainage: subgrade prep, overlaps, seams, anchoring and backfill — with the points contractors call out on the construction drawing.

Guide Vacuum preloading uses suction through wick drains instead of a heavy surcharge embankment. How the sealed system is built, where it beats surcharge, and when to combine the two.

Guide PVD, sand piles, bamboo piles or vacuum consolidation — which soft ground improvement method fits your depth, schedule and budget, and where each one stops working.

Guide Wick drains (PVD) cut soft-clay settlement that would take years down to months. The drainage principle, the install sequence, drain spacing and the design numbers that actually matter.

Comparison HDPE vs PVC geomembrane for ponds and containment: chemical resistance, UV life, flexibility and cost compared — plus where EPDM fits — so you pick the liner that survives your exposure.
Read guide
Comparison Geomembrane vs geotextile comes down to one thing: a geotextile is permeable and filters or reinforces soil; a geomembrane is impermeable and stops water. When you need each, and when you need both.
Read guide
Comparison Woven vs non-woven geotextile fabric solve opposite problems: woven reinforces and separates, non-woven filters and drains. Compare strength, permeability and the geotextile types/classes so you spec the right one.

Guide Pick HDPE geomembrane thickness by the job: 0.5 mm for small ponds, 1.0 mm for reservoirs, 1.5 mm for landfill and containment. What the subgrade and design life really dictate.
