Artificial Turf Installation
Base, Drainage & Why It Smells or Floods (2026)

Why installation matters more than the turf

Two gardens can use the same artificial turf and end up completely different. One stays flat, drains straight after a storm and looks the same years later. The other ripples, has soggy patches, grows weeds through the joins and starts to smell. The difference is almost never the turf; it is what was built underneath it.

Artificial turf is not waterproof. Its backing is perforated so rain passes through into the layer below. That makes the base the real drainage system. If the base cannot take the water away, the turf sits on a wet sponge.

The layers of a proper installation

Choosing the turf grade

Turf is sold by pile height and density. Our turfing cost guide groups it into four grades, supplied and laid (indicative 2026, Klang Valley):

The same guide notes that for a residential garden, mid-range 30–35 mm turf is the most popular choice. Base work is priced on top of the turf, which is why two quotes for the same turf can differ so much.

What the base work costs

Our turfing guide lists the ground preparation separately from the turf supply and lay. These are the lines that matter for artificial turf:

• Old turf and weed removal and disposal: RM0.50–RM1.50 per sq ft, depending on what is there.
• Ground levelling (soil cut and fill): RM0.80–RM2.50 per sq ft for minor correction; more for real re-grading.
• Weed membrane (geotextile): RM0.60–RM1.20 per sq ft.
• Drainage aggregate base for areas that drain poorly: RM1.50–RM3.50 per sq ft for the crushed-stone layer.

A quote that has the turf price but no base lines is not cheaper; it is a different, weaker job. Ask for each layer to be listed.

Why artificial turf floods or stays wet

• Laid on clay or compacted soil with no stone sub-base, so water has nowhere to go.
• No falls: the ground was levelled flat, or slopes towards the house instead of a drain.
• Laid on flat concrete without drainage mats, falls or outlets, so water ponds under the backing.
• Blocked drainage holes from silt, leaves or a membrane laid wrong way up.
• The garden itself floods: surface drains, a low garden or a neighbour’s run-off. Turf cannot fix that; see our sump pump and drainage guide.

A simple check tells you which problem you have. After heavy rain, lift a corner of the turf where the water sits. If the layer underneath is soil or clay with water standing on it, the base was never built to drain. If there is stone underneath but it is clogged with silt, the base needs cleaning or rebuilding. If the base drains but the whole garden is under water, the problem is the garden’s drainage, and the turf is only showing it. Each of these has a different fix, so it is worth knowing which one you are dealing with before anyone quotes to lift and relay the turf.

Why artificial turf smells

A smell usually means organic matter is sitting in water. The common causes are pet urine that soaks into the infill and base faster than it can be rinsed away, leaves and soil decomposing in the fibres, and a base that stays wet. The cure starts with drainage: a base that drains lets you rinse the turf properly. For pet areas, rinse regularly, remove waste promptly and choose a grade and infill suited to pets; our condo pet rules guide covers the building side for condo owners.

Turf on balconies, roofs and concrete

Laying turf on a balcony, rooftop or concrete patio is a different job from a garden. The turf must not block the floor drains or the falls that take rain off the slab, and it should be possible to lift it to check the waterproofing underneath. A slab that leaks under turf is hard to find and harder to fix. Our balcony waterproofing guide and rooftop terrace waterproofing guide explain why the membrane comes first.

Joins, edges and infill

Seams are where cheap installs show. The rolls should run in the same direction so the fibres lean the same way, and the joins should be bonded on joining tape, not just pushed together. Edges are pinned or fixed to an edging so they cannot lift and trip someone. Infill, usually sand, is brushed into the fibres to hold them upright and weigh the turf down; too little and the turf creases and moves.

Looking after artificial turf

• Brush against the grain now and then to lift the fibres.
• Blow or rake off leaves before they break down in the fibres.
• Rinse pet areas often; clear any spills.
• Keep hot items, barbecues and cigarettes off the turf.
• Check edges and seams after heavy rain and fix a lifting edge early.

Our garden maintenance contract guide notes that a garden with artificial turf needs no mowing at all; the visits become beds, leaf litter and a periodic deep clean.

How ClickBina can help

Artificial turf is often part of a wider outdoor job: drainage, a car porch, a patio or a garden makeover. ClickBina handles whole-house refurbishment and coordinates the trades on one job. WhatsApp us your job details for a quote: the area’s rough size, what is there now (soil, old grass or concrete) and whether it floods or smells. We reply within the hour, the price we agree is a flat price with no hidden charges, and a site visit is RM150, waived if you go ahead.
