Conqor Hydracure Blanket Application

To ensure that all Markham applicators are provided with the required level of knowledge and training to be competent in laying Conqor Hydracure blanket.

Step 1 of 27

1. Purpose

Step 7 of 27

7. Pre-Installation Inspection

Before laying the blanket:

Confirm the slab is ready for curing.
If AQURON has just been applied, ensure the application has been completed correctly.
Inspect the slab for defects or obstructions.
Remove debris where possible.
Report any defects in accordance with the Defect Notice SOP.
Confirm access to the entire slab.

Do not commence installation until any critical defects have been resolved.

Step 8 of 27

Measure slab, and calculate the overall area in m2 (length x width.)

Step 9 of 27

8. Measure the Slab

Measure:

Length
Width

Calculate:

Area (m²) = Length × Width

Record the total area within the project documentation.

Step 10 of 27

9. Calculate Blanket Requirements

One roll of CONQOR Hydracure Blanket covers approximately:

324 m²

Calculate the number of rolls required:

Total Area ÷ 324 = Number of Rolls

Example

1,000 m² ÷ 324 = 3.09 rolls

Minimum required: 4 rolls

Always allow additional blanket for:

200 mm overlaps
Irregular slab shapes
Waste
Repairs around penetrations

Never arrive on site with only the calculated minimum quantity.

Step 11 of 27

10. Application Procedure

Step 1 – Pre-Wet the Slab

The blanket works by retaining moisture already present within the concrete.

Before laying each strip:

Thoroughly wet the slab.
The surface should appear flooded.
Walking across the slab should create a visible splash.

Insufficient water will reduce curing effectiveness.

Step 12 of 27

Step 2 – Position the Blanket

Whenever practical:

Roll the blanket along the longest edge of the slab.

Consider:

Wind direction.
Site access.
Doorways.
Obstacles.

Choose the safest and most efficient installation direction.

Step 13 of 27

Step 3 – Lay the Blanket

Position the roll on the slab edge.

As the blanket is rolled out:

Keep it aligned with the slab edge.
Continuously spray water ahead of the roll.
Maintain a visible "wake" of water ahead of the blanket.

If the wake disappears:

Stop rolling.
Re-wet the slab.
Continue only when adequate moisture has been restored.

The blanket should quickly change from white to a darker colour as it absorbs moisture.

Step 14 of 27

Step 4 – Trim Blanket Ends

At the slab edge:

Roll slightly past the slab.
Wet the excess blanket.
Cut neatly using heavy-duty scissors.
Lay the trimmed section flat.

Step 15 of 27

Step 5 – Install Additional Strips

Repeat the process across the slab.

Each strip must overlap the previous strip by a minimum of:

200 mm

Wet each overlap before placing the next strip to ensure good adhesion and moisture retention.

Step 16 of 27

Step 17 of 27

Step 6 – Maintain Alignment

Install slowly and accurately.

If the blanket begins to drift:

Stop immediately.
Re-align the roll.
Continue once straight.

Straight blanket lines ensure:

Consistent overlaps.
Improved curing.
Easier removal.

Step 18 of 27

Step 7 – Remove Air Pockets

If air bubbles develop:

Sweep them along the length of the blanket.
Do not attempt to sweep across the width.

Internal stitched barriers prevent air moving sideways.

The objective is to make full contact between the blanket and the concrete surface.

Step 19 of 27

Step 8 – Work Around Obstructions

Where pipes or penetrations occur:

Select the most suitable method:

Cut a hole around the penetration.
Wrap a separate blanket section around the obstacle.
Cut and restart beyond the obstruction.

Maintain full slab coverage wherever possible.

If unsure, contact your Supervisor or the Markham office before proceeding.

Step 20 of 27

Step 9 – Secure the Blanket

Using CONQOR Hydracure Rippa Tape:

Secure blanket overlaps every 2–3 metres.
Firmly press tape onto the blanket.

For exposed sites or windy conditions:

Use water-filled buckets or approved weights in place of tape where appropriate.

This reduces blanket movement caused by wind or site traffic.

Step 21 of 27

11. High Wind Procedure

Do not install blanket when winds exceed approximately:

25 km/h
13 knots

If conditions prevent installation:

Maintain slab moisture using sprinklers or regular water application.
Obtain approval from the Site Manager before using sprinklers.
Return when weather conditions improve.
Secure blanket using additional weights if required.

Step 22 of 27

12. Blanket Inspection During Curing

Internal Slabs

Inspect approximately:

3–4 days after installation

External Slabs

Inspect:

Every 1–2 days

Check for:

Lifted edges.
Dry areas.
Damage.
Wind movement.
Ponding.

Where exposure occurs:

Wet the slab immediately.
Reposition the blanket.
Secure with tape or weighted buckets.

Step 23 of 27

13. Blanket Removal

Remove the blanket after:

7–8 days

Removal should preferably be completed by two people.

One person:

Lifts the blanket.

Second person:

Operates the floor scrubber immediately behind.

Remove the blanket one strip at a time.

Do not expose large areas of concrete before scrubbing, as surface residue may dry and become difficult to remove

Step 24 of 27

14. Scrubbing Procedure

Complete two scrubbing passes.

First Pass

Scrub without vacuum suction.
Apply clean water.
Allow the slurry to remain briefly on the surface.

Second Pass

Scrub again.
Operate with vacuum suction engaged.
Remove all slurry and residue.

Inspect the finished surface before leaving site.

Step 25 of 27

15. Equipment Cleaning

Immediately after use:

Empty the scrubber.
Flush clean water through the system.
Remove all slurry and residue.
Clean brushes and recovery tanks.

Do not allow product residue to dry inside equipment.

Step 26 of 27

16. Quality Assurance Requirements

Record the following:

Slab dimensions.
Blanket quantity used.
Installation date.
Weather conditions.
Inspection dates.
Corrective actions taken.
Removal date.
Photographs before, during and after installation.

Upload all documentation to the relevant MJM project and complete ITP
