How SUPER BLOC works

From dry storage to a working flood barrier in five minutes. Here's the science and the steps.

Activation

Four steps. Five minutes. Zero sand.

1

Place in water

Put the dry bag into a bucket of water, or directly into a puddle. The non-woven fabric wicks water inside.

2

Superabsorbent polymer swells

SAP particles inside absorb 500× their weight in water, forming a dense gel that stays locked inside the fabric.

3

Reaches 16 kg in 5 min

The bag fully activates, taking on the shape and weight of a sandbag — without any sand, any shovels, or any effort.

4

Deploy & stack

Use the reinforced handle to carry and throw bags into place. Stack them higher than the expected water level.

The technology

A patent-pending single-layer design

Most water-activated flood bags use two layers of fabric — one outer layer and an inner liner to trap the swollen gel. SUPER BLOC uses a single high-strength non-woven fabric (polyester + polyamide/viscose) that is hydrophilic enough to let water in fast, but tight enough to trap every SAP particle inside.

That means simpler manufacturing, lower cost, faster water ingress, and — crucially — enough durability to stitch on a carrying handle that can take the full 16 kg swung from one hand.

Unique to SUPER BLOC

The handle changes everything

A 16 kg bag without a handle has to be lifted with two hands, against your body. One person, one bag, slow progress.

With SUPER BLOC's reinforced stitched handle, a single person can pick up 2–4 activated bags with one hand, throw them into position, or chain them along a driveway in seconds. In an emergency, that multiplier is the difference between a saved basement and a flooded one.

Applications

Where SUPER BLOC works best

Anywhere you need to stop, slow, or redirect water — quickly and without heavy equipment.

Residential

Protect doors, garages, basements, and pools before a storm. Keep a pack in the garage year-round.

Commercial & Industrial

Warehouses, data centers, parking structures, retail frontage. Deploy without shutting down operations.

Municipal & Emergency

Stockpile at fire stations and civil-defense depots. Deploy in minutes when rivers rise or storms hit.

Construction sites

Divert runoff away from excavations, foundations, and unfinished structures. Redirect water to drains.

Agriculture & rural

Reach remote farms and villages where sand trucks can't go. Protect barns, greenhouses, and equipment.

Event & temporary

Outdoor events, film sets, festivals. Deploy quickly, store compactly, reactivate if dried.

Guidelines

Using SUPER BLOC safely

Do ✓

  • ✓ Place the bag in a bucket of fresh water, or in a puddle up to 10 cm deep.
  • ✓ Stack bags higher than the expected water level.
  • ✓ Use the handle for carrying and for throwing bags into position.
  • ✓ Activate before the flood begins — activation takes longer in cold water.
  • ✓ If a dried-out bag needs to be reactivated, just add water.
  • ✓ After use, let bags dry fully and dispose with household waste.

Don't ✕

  • ✕ Do not use with salt water. The SAP gel is designed for fresh water only.
  • ✕ Do not use the bags as seating or stepping surfaces.
  • ✕ Do not cut open an activated bag — the gel is non-toxic but slippery.
Safe for humans, pets, and environment
The SAP used in SUPER BLOC is non-toxic and widely used in hygiene products. No special PPE required.
