Questions Asked in Block Paving Interview
Q 1. Describe your experience with different types of paving blocks.
My experience encompasses a wide range of paving blocks, from the common concrete blocks in various colors and textures to permeable paving options designed for better water management, and even the more aesthetically pleasing natural stone blocks. I’ve worked extensively with different sizes and shapes, including rectangular, square, and even more intricate patterns like herringbone. Each type presents unique challenges and opportunities. For example, concrete blocks offer affordability and durability, while natural stone provides a high-end, visually appealing finish but requires more careful handling and installation. Permeable paving offers environmental benefits but needs careful consideration of the sub-base to ensure proper drainage.
- Concrete Blocks: The workhorse of block paving, offering a wide range of colours and finishes at a competitive price point. I frequently specify these for driveways and patios.
- Permeable Blocks: These blocks allow water to drain through, reducing surface runoff and mitigating flood risks. Ideal for environmentally sensitive areas.
- Natural Stone Blocks: These add a touch of elegance and sophistication but demand precision in installation and are generally more expensive.
Q 2. Explain the process of sub-base preparation for block paving.
Sub-base preparation is crucial for a successful block paving installation. Think of it as the foundation of a house – if it’s not done correctly, the entire structure will suffer. The process typically involves these steps:
- Excavation: Digging to the required depth, usually around 150-200mm depending on the project and local ground conditions. It’s essential to achieve a level base.
- Compaction: Using a vibrating plate compactor to consolidate the existing ground. This prevents settling and ensures a stable base.
- Type 1 MOT (or equivalent): Laying a layer of Type 1 MOT (a crushed stone aggregate) to a specified depth, usually 100-150mm. This provides a strong, free-draining base.
- Compaction (again!): Another pass with the compactor to compact the Type 1 MOT, ensuring it’s firm and even.
- Wastage Allowance: Allow for a 50-100mm loss of level during compaction
- Geotextile Membrane (optional): In some cases, a geotextile membrane is laid between the existing ground and the Type 1 MOT to prevent the sub-base from mixing with the soil.
Proper compaction is vital at each stage to prevent future settling and damage to the paving.
Q 3. What are the key considerations for drainage in block paving installations?
Drainage is paramount in block paving. Poor drainage leads to puddles, erosion, and ultimately, damage to the paving. Key considerations include:
- Sub-base Permeability: Using free-draining materials like Type 1 MOT ensures water can readily percolate through the layers.
- Falls/Gradients: Creating a slight fall (slope) away from buildings and towards designated drainage points, like gullies or soakaways, is essential to direct water flow. A typical fall is around 1:80 (1cm fall per 80cm).
- Permeable Paving: Choosing permeable paving blocks allows water to drain directly through the paving surface, reducing surface runoff.
- Drainage Channels: Incorporating channels or drains where necessary to collect and direct excess water away from the paved area.
- Soakaways/French Drains: In areas with poor natural drainage, these can be used to disperse water into the ground.
Careful planning and execution of the drainage aspects significantly influence the longevity and aesthetic appeal of the block paving.
Q 4. How do you ensure the correct compaction of the sub-base?
Correct compaction is achieved using a vibrating plate compactor. The process isn’t just about running the machine over the surface; it requires a systematic approach.
- Overlapping Passes: Overlapping each pass by about 50% ensures thorough compaction across the entire area.
- Multiple Passes: Several passes are usually required to achieve optimal compaction. The number of passes depends on the material and its moisture content.
- Moisture Content: The material shouldn’t be too dry or too wet. Too dry, and it won’t compact effectively; too wet, and it can become overly dense and less permeable. Ideal moisture content is achieved by adding water and then compacting until the target level and density are reached.
- Checking Compaction: Regular checks using a compaction gauge or density test are essential to verify that the required compaction levels are achieved.
I always aim for 95% compaction, ensuring the sub-base is stable and durable, preventing future settling.
Q 5. Describe your experience with different jointing methods for block paving.
Various jointing methods exist, each with its own advantages and disadvantages:
- Joint Filling Sand: The most common method, using a kiln-dried, fine-grained sand to fill the gaps between blocks. It provides a stable, aesthetically pleasing finish. This method requires careful sweeping to ensure all the gaps are fully filled.
- Resin Jointing: More durable and weed-resistant than sand. It involves filling the joints with a resin-based material, creating a seamless and long-lasting finish. It is more expensive and more difficult to repair any broken blocks that may occur after it is installed.
- Mortar Jointing: Less common for block paving, more typical for some masonry installations. It involves filling the joints with mortar, offering excellent strength and durability, though less permeable and more inflexible.
My choice of method depends on the project’s specific requirements, the budget, and the desired aesthetic.
Q 6. What are the common issues encountered during block paving installation, and how do you address them?
Common issues include:
- Uneven Sub-base: Leading to uneven paving and potential settling. This is addressed by careful preparation and compaction of the sub-base. Laser levels and compaction gauges are essential for this part of the process.
- Poor Drainage: Causing puddles and damage. This requires correct grading and drainage solutions, as previously discussed.
- Weed Growth: Especially with sand joints. Using weed-resistant jointing materials, or regularly weeding, helps mitigate this. Pre-emergent herbicides can be used as well.
- Block Settling: Caused by insufficient compaction. Proper compaction is crucial to avoid this.
- Incorrect Block Laying: leading to an uneven finish, and possible cracking. Using string lines and levels is essential for achieving accurate block placement.
Addressing these issues requires careful planning, attention to detail during installation, and the use of appropriate materials and techniques. Regular inspections throughout the process is also valuable in mitigating these issues.
Q 7. How do you calculate the required quantity of paving blocks for a project?
Calculating the required quantity involves these steps:
- Measure the Area: Accurately measure the area to be paved in square meters (m²). For irregular shapes, break the area into smaller, easier-to-measure sections.
- Block Size: Determine the dimensions of the paving blocks in meters. For example, 200mm x 100mm block would be 0.2m x 0.1m.
- Calculate Blocks per m²: Divide 1m² by the area of a single block. For example, for a 0.2m x 0.1m block:
1 m² / (0.2m * 0.1m) = 50 blocks per m² - Total Number of Blocks: Multiply the area to be paved (in m²) by the number of blocks per m². This calculation does not take into account wastage, cuts, or unusable blocks.
- Wastage Allowance: Add a wastage allowance of 5-10%, depending on the complexity of the design and cuts required.
For example, a 10m² area using 0.2m x 0.1m blocks would require: 10 m² * 50 blocks/m² = 500 blocks. Adding a 10% wastage allowance: 500 blocks * 1.1 = 550 blocks
Q 8. Explain the importance of using appropriate tools and equipment for block paving.
Using the right tools and equipment in block paving is paramount for efficiency, quality, and safety. Think of it like baking a cake – you wouldn’t try to bake a perfect soufflé with just a spoon and a bowl! The wrong tools lead to poor workmanship, delays, and potential injury.
Base Preparation: A vibrating plate compactor is essential for achieving a stable, compacted sub-base. Using a shovel alone will result in an uneven base, leading to settling and block movement later on.
Block Laying: A rubber mallet is crucial for gently tapping blocks into place, ensuring evenness and preventing damage. A sledgehammer would be far too forceful.
Cutting and Shaping: A professional angle grinder with a diamond blade is necessary for precise cuts, whereas a hand saw would be cumbersome and likely to result in inaccurate and chipped edges.
Joint Filling: Specialized jointing tools ensure proper filling and compaction of the sand or mortar, critical for preventing weed growth and ensuring longevity. A simple trowel wouldn’t achieve the necessary compaction.
Investing in quality, appropriate tools is an investment in the overall success and longevity of the project.
