CQ Soil Testing’s Post

We've had lots of rain lately. So, how does heavy rains affect your planned or current construction project? Prolonged rainfall events can greatly impact soil conditions, affecting its stability, strength, and suitability for construction. Saturated soils can lose their load-bearing capacity, while expansive clay soils can swell significantly, causing structural challenges. Additionally, stormwater runoff can erode topsoil, alter the natural soil profile, and deposit sediment that obscures the true characteristics of the site. To ensure accurate site classification, it is important to consider the timing of soil investigations to account for seasonal variations in soil conditions. By addressing the challenges posed by heavy rains and storms, construction projects in Queensland can achieve safer, more reliable foundations and long-term stability.

Some practices for stormwater, erosion, and sediment control in construction projects: • Avoid landscape disturbance. • Isolate disturbed areas with earth dikes, wattles, or silt fences. • Divert stormwater to sediment traps, stabilize soil, and control dust during construction. #التشييدـالمستدام #sustainabilty #construction

When preparing a construction site, it's important to consider the soil conditions and when the ground may be unsuitable. So what makes an unsuitable ground? Some of the common factors include: 🛑 Low soil bearing capacity: soils like peat and sand can't handle heavy loads 🛑 High water table: waterlogged soil can weaken the ground stability 🛑 Hidden hazards such as unmarked infrastructure and old foundations may exist underground. Luckily we've got the solution! Our ground protection mats help to distribute the weight, stabilise the ground, and protect against any other challenges that you could face.

🏗️ Curious about V-Drains in civil works? Let's dive in! 🌊 V-Drains are essential features in infrastructure projects designed to manage water flow. Shaped like a "V," these drains efficiently channel rainwater and prevent erosion by directing runoff away from critical areas like roads, embankments, and buildings. 🚧💧 Their clever design enhances drainage efficiency, reducing the risk of flooding and soil instability. From highways to residential developments, V-Drains play a vital role in ensuring our infrastructure remains resilient against water-related challenges. 🌍💪 Next time you spot these angled trenches, know they're silently working to keep our communities safe and our environments sustainable! 🌱✨ #CivilEngineering #Infrastructure #WaterManagement #onthemixservices

🌊 Water Industry News: Contract Agreement with Thames Water 🌊 Barhale has secured a £14.8 million contract with Thames Water to rehabilitate sections of the historic New River, one of London’s oldest water infrastructure assets. What you need to know: 🎯 This vital project will target areas in Hornsey and Waltham Cross to prevent leakage and extend the waterway's lifespan. 💪 They will be using a state-of-the-art Giken sheet piling system to strengthen the northern side of the waterway, minimizing noise and disturbance for the community. 🔎 Their innovative approach includes deploying pontoon barges for equipment access and silt excavation, ensuring they navigate the New River's constrained path efficiently. ⚒ At Waltham Cross, they will install sheet piling along a 1.1km stretch, reaching the impermeable London Clay to prevent water leakage. The gap between new and old piles will be filled with pea gravel for added stability. 🌍 Additionally, they are taking significant measures to protect the local ecology, including the use of a bubble curtain to prevent silt debris dispersal and to discourage fauna from approaching the works. 🤝 Barhale continues its relationship with Thames Water to collaborate on this essential refurbishment project, ensuring the longevity and efficiency of this historic waterway. Work is scheduled to commence in July 2024 with a target completion date of September 2025. #Barhale #ThamesWater #CivilEngineering #Infrastructure #Innovation #Sustainability #NewRiver

🌊 Detention vs. Retention Ponds: Understanding the Basics 🌱 As civil engineers, our role in sustainable land development often involves designing systems that manage stormwater effectively. Two commonly used methods are detention and retention ponds. While they may look similar, their functions and purposes are quite different: Detention Ponds 📉 - Purpose: Temporary storage of stormwater runoff to reduce peak flow and minimize flooding downstream. - Mechanism: Holds water only during and after rain events, slowly releasing it through controlled outlets. - Appearance: Normally dry between rain events, functioning as a "delay" mechanism in urban settings. Retention Ponds 🌊 - Purpose: Permanent storage to improve water quality by allowing sediments to settle and support natural ecosystems. - Mechanism: Always contains water (even during dry periods), with capacity to hold additional rainwater. - Appearance: Often resembles a small pond, blending into landscapes as a water feature and promoting biodiversity. Key Difference: Detention ponds are temporary and dry out between storms, whereas retention ponds are permanent, holding water continuously. Both help manage stormwater sustainably, but understanding their roles allows us to choose the best solution based on a project's unique needs. 💧 Whether for urban developments or natural landscapes, detention and retention ponds are crucial for reducing flood risks, protecting water quality, and enhancing biodiversity. #CivilEngineering #SustainableDevelopment #StormwaterManagement #LandDevelopment #GreenInfrastructure #WaterQuality #EngineeringDesign #EnvironmentalProtection #WeAreOlsson

🚧 The Hidden Dangers of Backfilled Construction Sites 🚧 When embarking on a construction project, choosing the right land is crucial. Backfilled land, although common, can pose significant risks if not properly managed. What is Backfilled Land? Backfilled land refers to sites where the original soil has been replaced or filled with other materials, often after excavation or to level uneven ground. The Risks: 1. Unstable Foundation: Improperly compacted backfill can lead to uneven settling, causing structural issues. 2. Water Drainage Problems: Backfilled soil often has poor drainage, increasing the risk of water damage and erosion. 3. Soil Contamination: Fill material may contain contaminants, posing health hazards and affecting vegetation. How to Mitigate These Risks: • Professional Soil Testing: Ensure comprehensive soil tests to assess stability and contamination. • Quality Fill Materials: Use high-quality, clean fill materials to minimize contamination. • Proper Compaction: Employ proper compaction techniques to ensure a stable foundation. Stay Safe, Build Smart! 🏗️🔍 #RealEstate #ConstructionSafety #BackfilledLand #MSLHomes #NairobiRealEstate

Listen to the sound difference between piling and soil mixing. Piling is first in this video. Soil mixing is quieter which is something to consider when working next to existing buildings whether houses, retail or offices etc Soil mixing also has reduced vibration: Soil Mixing induces very low vibrations, which reduces the potential impact to nearby utilities. The equipment does not exert any lateral pressure when mixing we can work as close as 200mm from the building/foundations. Soil Mixing/stabilisation is effective on different soils, including soft soils, flood plains, contaminated land, peat, silts and alluvium etc. Take a look at some of the applications of soil mixing https://lnkd.in/e5fSjKGQ #SoilMixing #DeepSoilMixing #SoilStabilisation #GroundEngineering #GeotechnicalEngineering #Construction #Piling #GroundRemediation #Brownfield
