If you’ve been searching for a reliable concrete repair solution, you may have come across the name “Waygo Cement.” But what exactly is it? Is it the right product for your project? In this guide, we answer the most common questions about Waygo Cement — straight, no fluff.
What is Waygo cement?
Quick Answer
Waygo Cement is a high-strength, single-component cement repair mortar manufactured by BOSLAI Waterproofing. It is specifically designed to repair defects in concrete pavements and floors — including pitting, hollow spots, spalling, delamination, cracks, and exposed reinforcement — with ultra-thin 3–5mm layer application and compressive strength up to 60 MPa at 28 days.
To put it simply: Waygo Cement is not regular cement. It is an engineered repair mortar that bonds directly to damaged concrete surfaces and restores them to full structural integrity — often stronger than the original surface.
Here’s what makes it different from ordinary cement:
- Single-component: Just add water. No separate primers or bonding agents required (though a primer can improve adhesion on highly porous surfaces).
- Ultra-thin application: Can be applied at just 3–5mm thickness, meaning you don’t need to demolish and replace the entire slab.
- Fast curing: Traffic can resume within 3 hours at room temperature. Walkable in approximately 6 hours.
- High compressive strength: 36 MPa at 7 days, 61 MPa at 28 days — strong enough for highways and industrial floors.
- Excellent bond strength: 1.9 MPa tensile bond at 28 days — it sticks to concrete like it belongs there.
Waygo Cement is suitable for a wide range of concrete surfaces:
- Highways and road surfaces
- Factory floors and industrial parks
- Parking lots and gas stations
- Warehouses and garages
- Bridges, steps, terraces, and roofs
- Driving schools and service areas

Is Waygo cement waterproof?
Quick Answer
No — Waygo Cement is not waterproof. It is a concrete repair mortar, not a waterproofing product. Its primary purpose is to repair and level damaged concrete surfaces (roads, floors, pavements) with high compressive strength and fast curing. If you need waterproofing, you should use a dedicated waterproofing product.
This is a common point of confusion, so let’s be crystal clear:
Waygo Cement Repair Mortar is designed for surface restoration — fixing potholes, spalling, cracks, and other defects in concrete. Its core strengths are:
- Compressive strength — up to 60 MPa at 28 days, ideal for heavy traffic
- Fast repair — traffic-ready within hours, not days
- Bond strength — adheres firmly to concrete substrates
- Wear resistance — holds up under high-pressure traffic conditions
It is not designed to stop water infiltration or act as a waterproof barrier. While it does have some water immersion resistance (1.3 MPa tensile bond after water immersion at 28 days), this is a durability feature — not a waterproofing function.
Need waterproofing too? For areas that require both repair AND waterproofing (like roofs, basements, or water tanks), apply Waygo Cement Repair Mortar first to fix structural defects, then apply a dedicated waterproofing coating such as BOSLAI’s waterproofing products over the repaired surface.
Does Waygo concrete repair work?
Quick Answer
Yes — Waygo Concrete Repair Mortar is highly effective and proven in real-world applications. It delivers up to 61 MPa compressive strength at 28 days, bonds strongly to concrete (1.9 MPa tensile bond), and resists cracking and debonding under high-speed, high-pressure traffic. Repaired surfaces can reopen to traffic within 3 hours, and it saves over 50% in cost and 60% in project time compared to traditional full-slab replacement.
Here’s why Waygo Cement Repair actually works — and works well:
1. Engineering-Grade Strength
The numbers speak for themselves:
| Property | 7 Days | 28 Days |
|---|---|---|
| Compressive Strength | 36 MPa | 61 MPa |
| Flexural Strength | 7.5 MPa | 10.9 MPa |
| Tensile Bond Strength | — | 1.9 MPa |
For context, typical concrete pavement has a compressive strength of 30–40 MPa. Waygo repair mortar exceeds that — meaning the repaired area is often stronger than the surrounding concrete.
2. Ultra-Thin Repair Without Demolition
Traditional concrete repair often requires breaking out and replacing entire slabs — expensive, time-consuming, and disruptive. Waygo Cement can be applied at just 3–5mm thickness directly onto the damaged surface. This means:
- No heavy demolition equipment needed
- 50%+ cost savings vs. traditional methods
- 60% faster project completion
- Minimal disruption to traffic and operations
3. Proven in Demanding Environments
Waygo Cement Repair Mortar has been used on highways, factory floors, bridge decks, and parking structures — environments that subject surfaces to constant heavy loads, vibration, and weather. Under high-speed and high-pressure traffic, it resists cracking and debonding.
Important: The repair will only work if the substrate is properly prepared. Waygo Cement Repair Mortar is a thin-layer repair agent. If you need to repair deeper areas (typically beyond 5mm), you should add small stones (aggregate) into the mix to provide bulk and structural integrity. For crack repair specifically, you must use a cutting machine to widen the crack into an inverted V-shape — this allows the mortar to fully penetrate to the bottom of the crack. Skipping this step will result in failure.
4. Real-World Performance Summary
| Feature | Performance |
|---|---|
| Traffic reopening | Within 3 hours (walkable in ~6 hours) |
| Cost vs. traditional repair | Saves over 50% |

| Color match | Minimal color difference with base concrete |
| Thermal expansion | Matches base concrete — no debonding from temperature changes |
| Working time | 20 minutes |
| Coverage | ~5 m² per 25kg bag at 3–5mm thickness |
How do you repair damaged cement?
Quick Answer
To repair damaged cement with Waygo Cement Repair Mortar:
(1) Clean the surface thoroughly;
(2) Saturate with high-pressure water;
(3) Remove standing water;
(4) Optionally apply bonding primer;
(5) Mix 25kg powder with 4.5L water for 5 minutes;
(6) Spread with a notched trowel at 3–5mm within 20 minutes;
(7) Roll with a spiked roller to remove air;
(8) Let it cure naturally. For cracks, cut into an inverted V-shape first. For deeper repairs, add small stones to the mix.
Here is the complete, step-by-step method to repair damaged cement using Waygo Cement Repair Mortar:
Step 1: Clean the Substrate
Remove all loose particles, dust, sand, debris. The cleaner the surface, the stronger the bond. Do not skip this step. Applying mortar over loose or unstable material will lead to cracking and failure.
Step 2: Saturate the Surface
Use a high-pressure water jet to thoroughly wet the surface. Keep spraying until the concrete stops absorbing water. This prevents the dry substrate from sucking moisture out of the fresh mortar, which would weaken the bond and cause delamination.
Step 3: Remove Standing Water
After saturation, remove any puddles or standing water with a sponge or cloth. The surface should be damp, not wet. Standing water will dilute the mortar and cause bubbles.
Step 4: Apply Bonding Primer (Optional but Recommended)
For highly porous or badly worn surfaces, apply a bonding primer or BOSLAI Concrete Surface Hardener using a cross-hatch method (one horizontal pass, one vertical pass). This significantly improves adhesion on difficult substrates.
Step 5: Mix the Mortar
Ratio: 1 bag (25kg) Waygo Cement Repair Mortar + 4.5 liters of clean water.
- Add water to the mixing container first, then add the powder
- Mix with a mechanical mixer for approximately 5 minutes
- Mix until uniform, lump-free, and free of air bubbles
- Do not over-water — excess water causes segregation and weakens the repair
Working time: 20 minutes. Only mix what you can apply within this window.
Step 6: Apply and Level
Pour the mixed mortar onto the prepared surface and spread with a notched trowel at 3–5mm thickness. Complete all pouring and leveling within the 20-minute working time.
For Crack Repair — Critical Step: Before applying the mortar, use a cutting machine to cut the crack into an inverted V-shape (wider at the top, narrowing toward the bottom). This allows the repair mortar to fully penetrate to the bottom of the crack and bond properly. If you simply fill the crack from the surface, the mortar won’t reach the base — and the repair will fail.
For Deeper Repairs (beyond 5mm): Waygo Cement Repair Mortar is designed as a thin-layer repair agent. For deeper voids or potholes, add small stones (aggregate) into the mixed mortar to provide bulk and structural strength. This extends the product’s capability to handle deeper damage without compromising performance.
Step 7: Remove Air Bubbles
Immediately after spreading, roll the surface with a spiked roller to release trapped air bubbles. This prevents voids from forming beneath the surface.
Step 8: Cure Naturally
No watering or special curing is needed. Allow natural curing:
- Walkable: ~6 hours after application
- Vehicle traffic: Theoretically within 3 hours, but recommended to wait until the next day for maximum durability
- If the surface dries too quickly in hot weather, a light mist spray can help
、
Important Precautions
- Apply only when temperature is above 5°C (41°F)
- Do not apply in rain or when rain is imminent
- Always wear rubber or plastic gloves — this product is for professional use
- Strictly control the water ratio — adding extra water to extend working time will reduce strength
- Shelf life: 6 months from production date. Store in a dry, cool place
