We study effects of strain on the electronic properties of the kagome latticein a tight-binding formalism with spin-orbit coupling (SOC). The degeneracy atthe $\Gamma$ point evolves into a pair of emergent tilted Dirac cones underuniaxial strain, where the anisotropy and tilting of the bands depend on themagnitude and direction of the strain field. SOC opens gaps at the emergentDirac points, making the flatband topological, characterized by a nontrivial$\mathbb{Z}_2$ index. Strains of a few percent drive the system into trivial ortopological phases. This confirms that moderate strain can be used to engineeranisotropic Dirac bands with tunable properties to study new phases in kagomelattices.
