Base Layer & Subgrade Preparation
Base Layer & Subgrade Preparation for Long-Lasting Road Construction in Navi Mumbai, Raigad, Thane, Pune, and Mumbai.
Shreeyash Construction provides professional base layer and subgrade preparation services for road construction, asphalt roads, bitumen roads, cement concrete roads, industrial roads, internal roads, approach roads, parking areas, and infrastructure projects.
A road is only as strong as its foundation. Before laying asphalt, bitumen, or cement concrete, proper subgrade preparation and base layer construction are required to improve road strength, load distribution, drainage performance, and long-term durability.
We provide base layer and subgrade preparation services across Navi Mumbai, Raigad, Thane, Pune, and Mumbai.
What is Subgrade Preparation?
Subgrade is the natural ground layer on which the road structure is built. It carries the load of all upper road layers and traffic movement.
Proper subgrade preparation includes excavation, levelling, grading, moisture control, soil improvement, and compaction. A weak subgrade can lead to road settlement, cracks, potholes, uneven surface, and early road failure.
What is Base Layer Preparation?
The base layer is constructed above the subgrade to provide strength and support to the final road surface. It helps distribute traffic load and creates a stable platform for asphalt, bitumen, or concrete road construction.
Base layer preparation may include GSB laying, WMM laying, granular filling, compaction, levelling, and slope correction as per project requirement.
Our Base Layer & Subgrade Preparation Services
1. Site Clearing & Ground Preparation
We clear unwanted material, debris, vegetation, soft soil, and unsuitable material before road foundation work begins.
2. Excavation & Cutting
We carry out excavation, cutting, and ground shaping as per required road level, slope, and alignment.
3. Filling & Leveling
We provide filling and levelling work to bring the ground to the required formation level for road construction.
4. Subgrade Compaction
The subgrade is compacted properly using suitable machinery to improve soil strength and prevent future settlement.
5. Soil Stabilization Support
Where required, we support soil improvement and stabilization to increase load-bearing capacity and road foundation strength.
6. GSB Layer Preparation
Granular Sub Base is laid and compacted to improve drainage, load distribution, and road stability.
7. WMM Layer Preparation
Wet Mix Macadam is laid above the GSB layer to create a strong base for asphalt, bitumen, or concrete road construction.
8. Slope & Camber Formation
We prepare proper road slope and camber to allow water flow and reduce surface water accumulation.
9. Final Level Checking
Before surface work begins, road levels, alignment, thickness, slope, and compaction are checked properly.
