BASE E SUB-BASE
A fundação que garante durabilidade, segurança e economia em cada pavimento.
BASE E SUB-BASE
Nenhum pavimento é durável sem uma boa estrutura de base e sub-base. Essas camadas são responsáveis por distribuir as cargas do tráfego, evitar recalques e preparar o terreno para receber o revestimento final.
Na CBI Engenharia, executamos a base e sub-base com critérios técnicos rigorosos, selecionando materiais adequados, aplicando espessuras ideais e realizando compactações de acordo com as normas. Esse cuidado garante suporte uniforme, estabilidade e maior vida útil ao pavimento, reduzindo riscos de fissuras e deformações.
Mais do que preparar o solo, entregamos confiabilidade e economia a longo prazo, criando a estrutura necessária para que rodovias, ruas, pátios e áreas industriais tenham desempenho superior.

Por que a base e a sub-base são decisivas para a vida útil do pavimento?
Quando mal executadas, surgem recalques, fissuras e altos custos de manutenção.
Quando bem feitas, garantem estabilidade, durabilidade e economia a longo prazo.
Por que a base e sub-base são tão importantes?
- Garantem estabilidade e suporte ao pavimentoresidenciais
- Distribuem corretamente as cargas do tráfego
- Reduzem recalques e trincas no revestimento final
- Aumentam a durabilidade e diminuem a necessidade de manutenção
- Contribuem para a segurança e qualidade da obra
Como a CBI Engenharia atua
- Estudo do solo e escolha do material mais adequado (brita graduada, solo-cimento, entre outros)
- Execução com equipamentos de compactação modernos e controle tecnológico
- Alinhamento com as etapas de drenagem e pavimentação para garantir desempenho integrado
- Compromisso com qualidade, precisão e sustentabilidade em cada etapa
Você sabia?
Mais de 70% dos problemas em pavimentos surgem por falhas na execução da base e sub-base.
Na CBI Engenharia, essa etapa é tratada com rigor técnico: usamos materiais adequados, controle de compactação e espessura correta para garantir estabilidade e vida longa ao pavimento.

AINDA TEM DÚVIDAS?
A sub-base é a camada inicial de apoio, geralmente feita com materiais granulares que ajudam a distribuir cargas. Já a base é a camada superior, mais resistente, que recebe diretamente o revestimento (asfalto, concreto ou paver). Juntas, garantem a estabilidade do pavimento.
Podem ser utilizados brita graduada, solo-brita, solo-cimento, areia ou outros materiais granulares, sempre definidos de acordo com o tipo de solo, tráfego esperado e projeto técnico.
Sim. São elas que suportam as cargas do tráfego e evitam deformações. Sem base e sub-base adequadas, o pavimento apresenta falhas prematuras, como recalques e trincas.
A espessura é definida por estudo técnico que considera solo local, tráfego e vida útil esperada. Não existe medida única — cada projeto precisa de dimensionamento específico.
Depende da extensão da obra e das condições do solo. Em geral, é uma fase rápida, mas que exige rigor no controle de compactação para garantir qualidade.
Sim. Realizamos ensaios de compactação, umidade e resistência, garantindo que as camadas tenham o desempenho estrutural esperado.
Trincas, afundamentos, infiltrações e necessidade de manutenção precoce. Mais de 70% dos problemas em pavimentos vêm de falhas nessa etapa.
